Electronic communication reminder technology

ABSTRACT

Techniques are described for providing reminders for electronic communications. For instance, response patterns of a user are determined by communication type based on monitoring past response behavior of the user and the response pattern data is stored for the user by communication type. After storing the response pattern data for the user by communication type, a particular communication that is for the user and that is initiated by a first sender is received. A type of the particular communication is determined and response pattern data associated with the determined type of the particular communication is accessed. A response reminder time for the particular communication is set based on the accessed response pattern data associated with the determined type of the particular communication.

DETAILED DESCRIPTION

Techniques are described for providing reminders related to electroniccommunications. With the proliferation of electronic communicationtechnology, users are able to communicate with other users with relativeease, over great distances, and at a high frequency. Based on the easeof electronic communication, the volume of communications exchangedbetween users has increased and at least some users receive a largenumber of communications at a high rate. Given the volume ofcommunications, the users may have difficulty managing thecommunications and efficiently responding to all communications forwhich a response is desired. In the context of electronic mail, someusers have electronic mail inboxes that have a large number of messages,that are unmanageable, and that are a place where electronic mailmessages become lost or forgotten if not handled soon after reading theelectronic mail message. To assist users with managing a high volume ofcommunications and providing timely responses, response reminders may beautomatically provided to a user for stale communications that may havebeen lost or forgotten.

In certain circumstances, providing a large number of response remindersall at the same time or spacing may add to the problem of managing alarge volume of communications and may not effectively alert users toimportant communications. Accordingly, to better focus automatically setresponse reminders, the response reminders may be automatically providedto a user based on the user's past communication activity. In thisregard, timing of response reminders may be set based on a time the usertypically takes to respond to certain types of messages. Also, responsereminders may be set for certain types of messages to which the usertypically responds, but not set for certain types of messages to whichthe user typically does not respond. Using the user's past communicationactivity in setting reminders may enhance the quality of the remindersprovided and assist the user in responding to more importantcommunications.

In some implementations, reminders are set based on past communicationhistory of a user for particular types of communications. In theseimplementations, a reminder may be set based on prior sending rates,sending timing, response rates, and/or response timing by the user forparticular types of communications. The reminders may be reminders tosend a particular type of communication and/or reminders to respond to aparticular type of communication. The reminders may be applicable to anycommunication medium, such as electronic mail (email) messages, text orShort Message Service (SMS) messages, instant messages (IM), voicetelephone calls, etc.

For example, a communication system may track how a user responds toreceived communications and sets reminders for new communications basedon the tracked response patterns of the user. In the email context, thesystem tracks how long it takes the user to respond to particular typesof email messages and provides a reminder based on a time it typicallytakes the user to respond to a particular type of a newly-receivedemail. For instance, if the system determines that the user typicallyresponds to a particular sender's email messages within one day, thesystem provides a reminder to the user when the system determines thatthe user has received an email message from the particular sender andthe user has not responded within one day.

In some implementations, the system considers a percentage of time theuser responds to particular types of communications in determiningwhether to set a reminder at all for a newly-received communication. Inthese implementations, if the system determines that the user respondsto communications from a first sender less than fifty percent of thetime, the system determines not to set a reminder for a newcommunication received from the first sender. If the system determinesthat the user responds to communications from a first sender more thanfifty percent of the time, the system determines to set a reminder for anew communication received from the first sender.

In some examples, the system may consider other types of communicationsin addition to or instead of a sender of the communication. In theseexamples, the system may consider content of received messages intracking and evaluating past communication history. For instance, if thesystem determines that the user typically responds to shipping noticeswithin two hours, the system sets a reminder for a shipping notice fortwo hours from receipt, even if a sender of the shipping notice isdifferent than prior senders of shipping notices.

The electronic communication reminder technology described throughoutthis document may assist people with managing business and personalcommunications. For example, if the system determines that the usertypically responds to emails from the user's boss within one hour, areminder for an email received from the user's boss is set to one hourafter receipt or user perception of the boss's email. The system helpskeep track of electronic business communications, ensures that the userresponds to electronic business communications in a timely manner, andhelps the user manage the user's received communications. In anotherexample, if the system determines that the user typically responds toemails from the user's friend within one week, a reminder for an emailreceived from the user's friend is set to a week after receipt or userperception of the friend's email. In this regard, the system trackscommunication behavior for personal relationships and ensures thatcommunications between friends/family, etc. do not lapse for too long.

FIG. 1 is a diagram 100 that illustrates an example of providingcommunication reminders. As shown, a graphical user interface of anelectronic mail (email) system includes an email inbox 105 for a user.The email inbox 105 includes a list of displayed representations ofemails received for the user. Each displayed representation includes asender name of a sender of the email, a subject of the email, and aday/time of receipt of the email. Each displayed representation includesan activity indicator that shows whether the user has responded to theemail, the user has forwarded the email, or whether the user has takenno action with respect to the email. The list of representations ofreceived email in the email inbox 105 is ordered based on time ofreceipt of the emails. Other information may be displayed in the emailinbox 105 and other types of ordering may be used.

The graphical user interface of the email system also includes controlsfor handling emails using the email system. For example, the graphicaluser interface includes a new control 110, a delete control 115, a replycontrol 120, and a forward control 125. The new control 110 enables theuser to send a new email message when the new control 110 is selected.The delete control 115 enables the user to delete an email included inthe user's email inbox 105 when the delete control 115 is selected. Thereply control 120 enables the user to respond to an email included inthe user's email inbox 105 when the reply control 120 is selected. Theforward control 125 enables the user to forward an email included in theuser's email inbox 105 when the forward control 125 is selected. Othercontrol buttons 130 may be provided in the graphical user interface ofthe email system. The graphical user interface of the email systemfurther includes a menu list 135 that includes other input controls thatenable a user to control the email system.

The diagram 100 also shows tracked response data 140 for the userassociated with the email inbox 105. The tracked response data 140includes data generated by the email system monitoring past responsebehavior of the user and identifying response patterns of the user basedon the monitoring. The tracked response data 140 is stored in electronicstorage (e.g., any type of computer-readable storage medium, such as ahard disk, memory, etc.). The tracked response data 140 is updated asthe user responds to additional emails.

As shown, the tracked response data 140 includes past response behaviorof the user by sender of the email. For each sender, the trackedresponse data 140 includes a response rate of the user and a responsetime of the user. The response rate indicates how frequently the userresponds to email messages from a particular sender. For instance, theresponse rate may be a percentage computed by dividing a number of pastemail messages received from a particular sender for which the userresponded by a total number of past email messages received from theparticular sender. As one example, the user has responded to 90% ofemail messages received from Sender 3 (e.g., the email system determinesthat the user has received 10 email messages from Sender 3 and respondedto nine of them). As another example, the user has responded to 10% ofemail messages received from Sender 4 (e.g., the email system determinesthat the user has received 10 email messages from Sender 4 and respondedto one of them).

The response time data indicates how quickly the user typically respondsto email messages from a particular sender. For instance, the responsetime may be computed by determining a response delay each time the userresponds to an email message from the particular sender and computing arunning average of the determined response delays. As one example, theuser has responded to email messages received from Sender 1 on averagein 15 minutes (e.g., the email system determines that the user hasresponded to three email messages from Sender 1 with response times of 5minutes, 10 minutes, and 30 minutes, respectively). As another example,the user has responded to email messages received from Sender 6 onaverage in 8 hours (e.g., the email system determines that the user hasresponded to four email messages from Sender 1 with response times ofone hour, one day (i.e., 24 hours), five hours, and two hours,respectively).

The email system uses the tracked response data 140 to generate aresponse reminder list 150. The response reminder list 150 displays alist of response reminders for email messages included in the emailinbox 105 for which a response is overdue according to the user's pastresponse behavior as reflected by the tracked response data 140. Theresponse reminder list 150 is ordered based on an amount of timeresponses to the email messages are overdue, which may differ than anorder based on time of receipt of the email messages. The responsereminder list 150 may be displayed each time the user begins using theemail system (e.g., logs on, starts an email program, etc.), each timethe user controls an input device to initiate a new email message or newreply email message, each time the user controls an input device tohover over a graphical control (e.g., button) that initiates a new emailmessage or new reply email message, and/or each time a new reminder isadded to the list 150 based on a response becoming overdue or a responsedeadline approaching.

As shown, for the first email message included at the top of the emailinbox 105, the email system has automatically set a response reminderfor 4:15 PM on Feb. 20, 2009. More specifically, when the first emailmessage is received, the email system compares the sender of the firstemail message (Sender 1) to the tracked response data 140, identifies arecord corresponding to Sender 1, and accesses the response rate dataand response time data included in the identified record. The emailsystem determines whether to set a response reminder for the first emailmessage by comparing the accessed response rate data to a response ratethreshold (e.g., 50%, 25%, etc.). In this example, the email systemdetermines, based on the comparison, that the response rate of the userfor email messages received from Sender 1 (i.e., 85%) is greater thanthe response rate threshold and that a response reminder should be setfor the first email message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the first email message using the accessedresponse time data. In this regard, the email system determines that thefirst email message was received at 4:00 PM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 1 in 15 minutes. The email system thenadds 15 minutes to the determined 4:00 PM time of receipt andautomatically, without human intervention, sets a response reminder timefor the first email message as 4:15 PM on Feb. 20, 2009.

Based on the automatically set response reminder time for the firstemail message (i.e., 4:15 PM), the email system determines that, at 5:00PM on Feb. 20, 2009 when the response reminder list 150 is beingdisplayed, a response for the first email message is 45 minutes overdue.Accordingly, the email system displays a reminder entry in the responsereminder list 150 (i.e., the third entry in the list as shown) for thefirst email message. The displayed reminder entry indicates that thefirst email message was sent by Sender 1, has a subject of Subject 1,and that a response to the first email message is overdue by 45 minutes.Other information may be displayed in the reminder entry and other typesof reminders may be provided in addition to (or instead of) the responsereminder list 150.

For the second email message included in the email inbox 105, the emailsystem has automatically set a response reminder for 5:30 PM on Feb. 20,2009. More specifically, when the second email message is received, theemail system compares the sender of the first email message (Sender 2)to the tracked response data 140, identifies a record corresponding toSender 2, and accesses the response rate data and response time dataincluded in the identified record. The email system determines whetherto set a response reminder for the second email message by comparing theaccessed response rate data to a response rate threshold (e.g., 50%,25%, etc.). In this example, the email system determines, based on thecomparison, that the response rate of the user for email messagesreceived from Sender 2 (i.e., 65%) is greater than the response ratethreshold and that a response reminder should be set for the secondemail message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the second email message using the accessedresponse time data. In this regard, the email system determines that thesecond email message was received at 2:30 PM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 2 in 3 hours. The email system then adds 3hours to the determined 2:30 PM time of receipt and automatically,without human intervention, sets a response reminder time for the secondemail message as 5:30 PM on Feb. 20, 2009.

Based on the automatically set response reminder time for the secondemail message (i.e., 5:30 PM), the email system determines that, at 5:00PM on Feb. 20, 2009 when the response reminder list 150 is beingdisplayed, a response for the second email message is not yet overdue.Accordingly, the email system does not include a reminder entry in theresponse reminder list 150 corresponding to the second email messagebecause, in this implementation, the response reminder list 150 includesentries corresponding to email messages for which a response is overdue.In other implementations, the response reminder list 150 may includereminder entries corresponding to email messages for which a response isnot yet due. In these implementations, the email system may distinguish,in the response reminder list 150, the reminder entries corresponding tooverdue responses from reminder entries corresponding to responses thatare not yet due. For example, the email system may display an overduetime for reminder entries corresponding to overdue responses (as shownin FIG. 1) and display a “due in” time for reminder entriescorresponding to responses that are not yet due. The email system alsomay display reminder entries corresponding to overdue responses in afirst color (e.g., red) and display reminder entries corresponding toresponses that are not yet due in a second color (e.g., green). Theemail system further may display separate reminder lists for overdueresponses and responses that are not yet due.

In implementations in which a reminder list includes entries forresponses that are not yet due, the email system may display entries foronly a subset of the reminders for which a response is not yet due. Forexample, the email system may only include reminders for which aresponse is due within a threshold period of time (e.g., 1 day, 1 hour,etc.). In this example, the email system determines a time at which aresponse reminder is due, a current time, and whether a period of timebetween the current time and the time at which the response reminder isdue exceeds the threshold.

In response to a determination that the period of time exceeds thethreshold, the email system determines not to include an entrycorresponding to the response reminder in the response reminder list. Inresponse to a determination that the period of time is less than thethreshold, the email system determines to include an entry correspondingto the response reminder in the response reminder list. Limiting theresponse reminder list to response reminders that have deadlines thatare approaching may assist a user in prioritizing email messages towhich to respond.

Referring again to FIG. 1, for the third email message included in theemail inbox 105, the email system has cancelled a reminder set for thethird email message because the user has already responded to the thirdemail message. More specifically, when the third email message isreceived, the email system compares the sender of the third emailmessage (Sender 3) to the tracked response data 140, identifies a recordcorresponding to Sender 3, and accesses the response rate data andresponse time data included in the identified record. The email systemdetermines whether to set a response reminder for the third emailmessage by comparing the accessed response rate data to a response ratethreshold (e.g., 50%, 25%, etc.). In this example, the email systemdetermines, based on the comparison, that the response rate of the userfor email messages received from Sender 3 (i.e., 90%) is greater thanthe response rate threshold and that a response reminder should be setfor the third email message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the third email message using the accessedresponse time data. In this regard, the email system determines that thethird email message was received at 1:00 PM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 3 in 7 hours. The email system then adds 7hours to the determined 1:00 PM time of receipt and automatically,without human intervention, sets a response reminder time for the thirdemail message as 8:00 PM on Feb. 20, 2009.

After setting the response reminder time for the third email message,the email system monitors actions of the user with respect to the thirdemail message. In this example, the email system detects that the userresponds to the third email message based on the monitored actions ofthe user. In response to a detection that the user has responded to thethird email message, the email system cancels the automatically setreminder for the third email message. As such, the email system does notprovide a reminder for the third email message to the user at 8:00 PM onFeb. 20, 2009. In this regard, if the response reminder list 150 wasdisplayed at 8:00 PM on Feb. 20, 2009 or later, a reminder entry for thethird email message would be absent from the response reminder list 150.

For the fourth email message included in the email inbox 105, the emailsystem has determined not to set a response reminder for the fourthemail message because the user responds to email messages from thesender of the fourth email message at a relatively low rate. Morespecifically, when the fourth email message is received, the emailsystem compares the sender of the fourth email message (Sender 4) to thetracked response data 140, identifies a record corresponding to Sender4, and accesses the response rate data. The email system determineswhether to set a response reminder for the fourth email message bycomparing the accessed response rate data to a response rate threshold(e.g., 50%, 25%, etc.). In this example, the email system determines,based on the comparison, that the response rate of the user for emailmessages received from Sender 4 (i.e., 10%) is less than the responserate threshold and that a response reminder should not be set for thefourth email message. In response to determining that a responsereminder should not be set for the fourth email message, the emailsystem handles the fourth email message without setting or otherwiseproviding a reminder.

For the fifth email message included in the email inbox 105, the emailsystem has automatically set a response reminder for 12:00 PM on Feb.20, 2009. More specifically, when the fifth email message is received,the email system compares the sender of the fifth email message (Sender5) to the tracked response data 140, identifies a record correspondingto Sender 5, and accesses the response rate data and response time dataincluded in the identified record. The email system determines whetherto set a response reminder for the fifth email message by comparing theaccessed response rate data to a response rate threshold (e.g., 50%,25%, etc.). In this example, the email system determines, based on thecomparison, that the response rate of the user for email messagesreceived from Sender 5 (i.e., 70%) is greater than the response ratethreshold and that a response reminder should be set for the fifth emailmessage.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the fifth email message using the accessedresponse time data. In this regard, the email system determines that thefifth email message was received at 10:00 AM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 5 in 2 hours. The email system then adds 2hours to the determined 10:00 AM time of receipt and automatically,without human intervention, sets a response reminder time for the fifthemail message as 12:00 PM on Feb. 20, 2009.

Based on the automatically set response reminder time for the fifthemail message (i.e., 12:00 PM), the email system determines that, at5:00 PM on Feb. 20, 2009 when the response reminder list 150 is beingdisplayed, a response for the fifth email message is 5 hours overdue.Accordingly, the email system displays a reminder entry in the responsereminder list 150 (i.e., the first entry in the list as shown) for thefifth email message. The displayed reminder entry indicates that thefifth email message was sent by Sender 5, has a subject of Subject 5,and that a response to the fifth email message is overdue by 5 hours.Other information may be displayed in the reminder entry and other typesof reminders may be provided in addition to (or instead of) the responsereminder list 150.

For the sixth email message included in the email inbox 105, the emailsystem has automatically set a response reminder for 4:30 PM on Feb. 20,2009. More specifically, when the sixth email message is received, theemail system compares the sender of the sixth email message (Sender 3)to the tracked response data 140, identifies a record corresponding toSender 3, and accesses the response rate data and response time dataincluded in the identified record. The email system determines whetherto set a response reminder for the sixth email message by comparing theaccessed response rate data to a response rate threshold (e.g., 50%,25%, etc.). In this example, the email system determines, based on thecomparison, that the response rate of the user for email messagesreceived from Sender 3 (i.e., 90%) is greater than the response ratethreshold and that a response reminder should be set for the sixth emailmessage.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the sixth email message using the accessedresponse time data. In this regard, the email system determines that thesixth email message was received at 9:30 AM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 3 in 7 hours. The email system then adds 7hours to the determined 9:30 AM time of receipt and automatically,without human intervention, sets a response reminder time for the sixthemail message as 4:30 PM on Feb. 20, 2009.

Based on the automatically set response reminder time for the sixthemail message (i.e., 4:30 PM), the email system determines that, at 5:00PM on Feb. 20, 2009 when the response reminder list 150 is beingdisplayed, a response for the sixth email message is 30 minutes overdue.Accordingly, the email system displays a reminder entry in the responsereminder list 150 (i.e., the fifth entry in the list as shown) for thesixth email message. The displayed reminder entry indicates that thesixth email message was sent by Sender 3, has a subject of Subject 6,and that a response to the sixth email message is overdue by 30 minutes.Other information may be displayed in the reminder entry and other typesof reminders may be provided in addition to (or instead of) the responsereminder list 150.

For the seventh email message included in the email inbox 105, the emailsystem has automatically set a response reminder for 12:30 PM on Feb.20, 2009. More specifically, when the seventh email message is received,the email system compares the sender of the seventh email message(Sender 2) to the tracked response data 140, identifies a recordcorresponding to Sender 2, and accesses the response rate data andresponse time data included in the identified record. The email systemdetermines whether to set a response reminder for the seventh emailmessage by comparing the accessed response rate data to a response ratethreshold (e.g., 50%, 25%, etc.). In this example, the email systemdetermines, based on the comparison, that the response rate of the userfor email messages received from Sender 2 (i.e., 65%) is greater thanthe response rate threshold and that a response reminder should be setfor the seventh email message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the seventh email message using the accessedresponse time data. In this regard, the email system determines that theseventh email message was received at 9:30 AM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 2 in 3 hours. The email system then adds 3hours to the determined 9:30 AM time of receipt and automatically,without human intervention, sets a response reminder time for theseventh email message as 12:30 PM on Feb. 20, 2009.

Based on the automatically set response reminder time for the seventhemail message (i.e., 12:30 PM), the email system determines that, at5:00 PM on Feb. 20, 2009 when the response reminder list 150 is beingdisplayed, a response for the seventh email message is four hours and 30minutes overdue. Accordingly, the email system displays a reminder entryin the response reminder list 150 (i.e., the second entry in the list asshown) for the seventh email message. The displayed reminder entryindicates that the seventh email message was sent by Sender 2, has asubject of Subject 9, and that a response to the seventh email messageis overdue by four hours and 30 minutes. Other information may bedisplayed in the reminder entry and other types of reminders may beprovided in addition to (or instead of) the response reminder list 150.

The response reminder for the seventh email message is set and remainsactive despite the user having forwarded the seventh email message.Accordingly, unlike replying to the seventh email message (or deletingthe seventh email message), the user action of forwarding the seventhemail message does not impact the response reminder when detected by theemail system. In some implementations, when the email system detects aforwarding action related to an email message, the email system modifiesa reminder time of a reminder associated with the forwarded email. Inthese implementations, the email system may extend the reminder timebased on detection of the forwarding action because the forwardingaction indicates that the user has viewed the message and is takingaction to handle the message.

For the eighth and ninth email messages included in the email inbox 105,the email system has automatically set a single response reminder for4:30 PM on Feb. 20, 2009. More specifically, when the ninth emailmessage is received, the email system compares the sender of the ninthemail message (Sender 6) to the tracked response data 140, identifies arecord corresponding to Sender 6, and accesses the response rate dataand response time data included in the identified record. The emailsystem determines whether to set a response reminder for the ninth emailmessage by comparing the accessed response rate data to a response ratethreshold (e.g., 50%, 25%, etc.). In this example, the email systemdetermines, based on the comparison, that the response rate of the userfor email messages received from Sender 6 (i.e., 60%) is greater thanthe response rate threshold and that a response reminder should be setfor the ninth email message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the ninth email message using the accessedresponse time data. In this regard, the email system determines that theninth email message was received at 8:10 AM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 6 in 8 hours. The email system then adds 8hours to the determined 8:10 AM time of receipt and automatically,without human intervention, sets a response reminder time for the ninthemail message as 4:10 PM on Feb. 20, 2009.

Subsequent to setting the reminder for the ninth email message, theemail system receives the eighth email message. In response to receivingthe eighth email message, the email system compares the sender (Sender6) and subject (Subject 7) of the eighth email message to the responsereminders included in the response reminder list 150 and identifies areminder corresponding to Sender 6 and Subject 7 in the responsereminder list 150. Based on the identified reminder that exists for thesender (Sender 6) and subject (Subject 7) of the eighth email message,the email system determines to modify the set reminder based on receiptof the eighth email message, rather than setting another reminder forthe eighth email message.

To modify the set reminder, the email system compares the sender of theeighth email message (Sender 6) to the tracked response data 140,identifies a record corresponding to Sender 6, and accesses the responsetime data included in the identified record. In some examples, the emailsystem determines not to analyze the response rate data for Sender 6because a reminder has already been set for an email message receivedfrom Sender 6. Using the accessed response time data, the email systemdetermines that a response reminder for the eighth email message shouldbe set at 4:30 PM. Accordingly, the email system changes the setreminder time from 4:10 PM to 4:30 PM. The email system also may modifythe reminder time by computing a new reminder time that accounts forboth the reminder time of the eighth email message and the reminder timeof the ninth email message (e.g., an average).

In some implementations of handling multiple messages from the samesender and/or having the same subject, the email system computes adifference between a reminder time determined based on the latterreceived email message and a set reminder time based on the earlierreceived email message. In these implementations, the email systemcompares the computed difference in reminder time to a threshold (e.g.,30 minutes or one hour) and determines whether and how to modify the setreminder based on the comparison of the difference to the threshold. Forexample, when the comparison reveals that the difference is less thanthe threshold, the email system determines to adjust the reminder timeto that of the latter received email message. This example isillustrated by the eighth and ninth email messages included in the emailinbox 105 (e.g., 4:30−4:10=20, which is less than a threshold of 30minutes, so modify reminder time to 4:30). In other examples, when thecomparison reveals that the difference is less than the threshold, theemail system determines to maintain the reminder time set based on theearlier received email message (e.g., 4:30−4:10=20, which is less than athreshold of 30 minutes, so maintain reminder time to 4:10).

When the comparison reveals that the difference is greater than thethreshold, the email system may determine a new reminder time thataccounts for both the reminder time of the earlier received emailmessage and the reminder time of the latter received email message. Forinstance, the email system may compute an average of the two remindertimes and modify the set reminder time to be the computed average (e.g.,a midpoint between the two reminder times). In some examples, when thecomparison reveals that the difference is greater than the threshold,the email system may determine to set separate reminders for themultiple messages or may determine to maintain the set reminder time oruse the reminder time of the latter received email message.

In some implementations, the email system accelerates the set remindertime based on receipt of the additional email message from the samesender that has the same subject as a set reminder. In theseimplementations, the email system accelerates the reminder time becausethe sender appears to be anxiously seeking a response. For example, theemail system may modify the reminder time to a certain time period afterreceipt of the additional email message (e.g., 15 minutes). In anotherexample, the email system may reduce the set reminder time by a certaintime period (e.g., 30 minutes) based on receipt of the additional emailmessage.

The email system also may track response pattern behavior of therecipient in circumstances in which additional messages having the samesender and subject are received. The email system may use the trackedresponse pattern behavior of the recipient in these circumstances inmodifying the set reminder time.

Referring again to FIG. 1, based on the automatically set responsereminder time for the eighth and ninth email messages (i.e., 4:30 PM),the email system determines that, at 5:00 PM on Feb. 20, 2009 when theresponse reminder list 150 is being displayed, a response for the eighthand ninth email messages is 30 minutes overdue. Accordingly, the emailsystem displays a reminder entry in the response reminder list 150(i.e., the fourth entry in the list as shown) for the eighth and ninthemail messages. The displayed reminder entry indicates that the eighthand ninth email messages were sent by Sender 6, have a subject ofSubject 7, and that a response to the eighth and ninth email messages isoverdue by 30 minutes. The number two in parentheses adjacent to thereminder time indicates that the response reminder corresponds to tworeceived email messages. Other information may be displayed in thereminder entry and other types of reminders may be provided in additionto (or instead of) the response reminder list 150.

For the tenth and eleventh email messages included in the email inbox105, the email system has cancelled a set reminder because the user hasalready responded to the tenth email message. More specifically, whenthe eleventh email message is received, the email system compares thesender of the eleventh email message (Sender 3) to the tracked responsedata 140, identifies a record corresponding to Sender 3, and accessesthe response rate data and response time data included in the identifiedrecord. The email system determines whether to set a response reminderfor the eleventh email message by comparing the accessed response ratedata to a response rate threshold (e.g., 50%, 25%, etc.). In thisexample, the email system determines, based on the comparison, that theresponse rate of the user for email messages received from Sender 3(i.e., 90%) is greater than the response rate threshold and that aresponse reminder should be set for the eleventh email message.

In response to determining that a response reminder should be set, theemail system determines a response reminder time at which to provide theresponse reminder for the eleventh email message using the accessedresponse time data. In this regard, the email system determines that theeleventh email message was received at 7:45 AM on Feb. 20, 2009 and theaccessed response time data indicates that the user typically respondsto email messages from Sender 3 in 7 hours. The email system then adds 7hours to the determined 7:45 AM time of receipt and automatically,without human intervention, sets a response reminder time for theeleventh email message as 2:45 PM on Feb. 20, 2009.

Subsequent to setting the reminder for the eleventh email message, theemail system receives the tenth email message. In response to receivingthe tenth email message, the email system either sets another reminderfor the tenth email message or modifies a reminder time of the setreminder for the eleventh email message.

After setting one or more response reminders for the tenth and eleventhemail messages, the email system monitors actions of the user withrespect to the tenth and eleventh email messages. In this example, theemail system detects that the user responds to the tenth email messagebased on the monitored actions of the user. In response to a detectionthat the user has responded to the tenth email message, the email systemcancels the one or more automatically set reminders for the tenth andeleventh email messages because the tenth and eleventh email messagesare from the same sender and have the same subject. As such, the emailsystem does not provide a reminder for the tenth and eleventh emailmessages to the user. In this regard, the response reminder list 150does not include a reminder entry for the tenth email message or theeleventh email message.

In some examples, ordering of the response reminder list 150 may bedifferent from ordering of the user's inbox 105. In these examples, theresponse reminder list 150 may be ordered based on a combination of timeof receipt of an email message of a first type and an average responsetime by the user for email messages having the first type. Accordingly,the order in the response reminder list 150 may be quite different thanthe order in the email inbox 105 because the order in the responsereminder list 150 accounts for past response behavior/patterns, whereasthe email inbox may only account for time of receipt. In one example, afirst email may be received at time one and a second email may bereceived at time two that is later than (e.g., further in the future)than time one. In this example, a reminder for the second email may beprovided prior to a reminder for the first email because the usertypically responds to a second type of email corresponding to the secondemail more quickly than a first type of email corresponding to the firstemail.

In some implementations, ties in reminder time exist for automaticallyset reminders. Generally, ties in reminder time may be broken by time ofreceipt. However, the email system also may break ties based on whetheror not the email system has received multiple messages corresponding toa reminder.

In some implementations, the response reminder list 150 may includereminders that are not yet due and instead show a time by which aresponse is due, rather than overdue. In these implementations, theemail system may distinguish, in response reminder list 150, remindersfor which a response is overdue (e.g., highlight or display in adifferent color, such as red) from reminders for which a response is notyet due, but approaching.

Referring to FIG. 2, a block diagram of an electronic communicationsystem 200 is shown. The system 200 includes a client device 205, anetwork 280, and a communication provider 290. The network 280 enablesthe client device 205 and the communication provider 290 to exchangeelectronic communications.

The client device 205 includes an input module 210, a data store 220,reply pattern and reminder data 230, a processor 240, an input/output(I/O) device 250, and a memory 260. The client device 205 outputsreceived electronic communications to a user and allows a user to sendelectronic communications. For instance, the client device 205 allows auser to perceive received electronic communications and respond to thereceived electronic communications. The client device 205 may be aportable device (e.g., smart phone, tablet PC, laptop computer, etc.) ora desktop computer. The client device 205 may be implemented withinhardware or a combination of hardware and software.

The input module 210 imports data associated with communicationinterfaces. The data may include data resulting from received electroniccommunications. The data also may include data related to settings inputby a user that are used in handling electronic communications. The inputmodule 210 may input data from a device (e.g., the communicationprovider 290) connected to the network 280. In some implementations, theinput module 210 reformats and/or transforms the data such that the datamay be processed and stored by other components within the client device205.

The client device 205 also includes a data store 220. In someimplementations, data from the input module 210 is stored in the datastore 220. The data store 220 may be, for example, a database thatlogically organizes data into a series of database tables. The datastore 220 may be a hard disk drive, non-volatile memory (e.g., Flashmemory), or another type of electronic storage device.

The client device 205 also includes reply pattern and reminder data 230.The reply pattern and reminder data 230 may include tracked dataindicative of reply patterns by communication type and data defining setreminders. The reply pattern and reminder data 230 may include anycommunication pattern data and reminder data described throughout thedisclosure. In some implementations, the reply pattern and reminder data230 may be received, by the client device 205, from the communicationprovider 290, or may be stored, at least partially, by the communicationprovider 290.

The client device 205 also includes a processor 240. The processor 240may be a processor suitable for the execution of a computer program suchas a general or special purpose microprocessor, and any one or moreprocessors of any kind of digital computer. Generally, a processorreceives instructions and data from a read-only memory or a randomaccess memory or both. The processor 240 receives instructions and datafrom the components of the client device 205 to, for example, displayinterfaces related to electronic communications of a user. In someimplementations, the client device 205 includes more than one processor.

The client device 205 further includes the I/O device 250, which isconfigured to allow user input and display output. For example, the I/Odevice 250 may be a mouse, a keyboard, a stylus, a touch screen, a trackball, a toggle control, one or more user input buttons, a microphone, orany other device that allows a user to input data into the client device205 or otherwise communicate with the client device 205. In someimplementations, the user may be a machine and the user input may bereceived from an automated process running on the machine. In otherimplementations, the user may be a person.

The I/O device 250 also may include a device configured to outputelectronic communications. For instance, the I/O device 250 may includea display device configured to display graphical user interfaces thatenable a user to perceive electronic communication information andenable a user to interact with the client device 205. The I/O device 250also may include a speaker configured to provide audible output relatedto electronic communication information (e.g., audible electroniccontent or reminders).

The client device 205 also includes a memory 260. The memory 260 may beany type of tangible machine-readable storage medium. The memory 260may, for example, store the data included in the data store 220. In someimplementations, the memory 260 may store instructions that, whenexecuted, cause the client device 205 to, for example, process anddisplay electronic communications. The memory 260 may store instructionsthat, when executed, cause the client device 205 to perform operationsdescribed throughout the disclosure.

The electronic communication system 200 also includes a network 280. Thenetwork 280 is configured to enable exchange of electroniccommunications between devices connected to the network 280. Forexample, the network 280 may be configured to enable exchange ofelectronic communications between the client device 205 and thecommunication provider 290. The network 280 may include, for example,one or more of the Internet, Wide Area Networks (WANs), Local AreaNetworks (LANs), analog or digital wired and wireless telephone networks(e.g., a PSTN, Integrated Services Digital Network (ISDN), a cellularnetwork, and Digital Subscriber Line (DSL)), radio, television, cable,satellite, or any other delivery or tunneling mechanism for carryingdata. Network 280 may include multiple networks or subnetworks, each ofwhich may include, for example, a wired or wireless data pathway. Thenetwork 280 may include a circuit-switched network, a packet-switcheddata network, or any other network able to carry electroniccommunications. For example, the network 280 may include networks basedon the Internet protocol (IP) or asynchronous transfer mode (ATM).

The communication provider 290 is an electronic device configured toexecute programs and exchange communications with the client device 205(e.g., multiple client devices) over the network 280. For example, thecommunication provider 290 may be configured to execute a program thatperforms electronic communication processing operations. In thisexample, the communication provider 290 may exchange communications withthe client device 205 to receive input associated with electronicmessages and provide reminders output to the client device 205.

Although the example client device 205 is shown as a single integratedcomponent, one or more of the modules and applications included in theclient device 205 may be implemented separately from the device 205 butin communication with the device 205. For example, the data store 220may be implemented on a centralized server that communicates andexchanges data with the client device 205. In this example, thecommunication provider 290 may communicate with the client device 205and perform operations described throughout the disclosure as beingperformed by the client device 205 or may perform operations that assistin the client device 205 in performing described operations.

FIGS. 3, 5, 16, 18, 21, 30, 34, 36, 38, and 40 illustrate exampleprocesses. The operations of the example processes are describedgenerally as being performed by the system 200. The operations may beperformed exclusively by the client device 205, may be performedexclusively by the communications provider 290, or may be performed by acombination of the client device 205 and the communications provider290. In some implementations, operations of the example processes may beperformed by one or more processors included in one or more electronicdevices.

FIG. 3 illustrates an example of a process 300 for storing responsepattern data. The system 200 receives communications for a user (310).For instance, the system 200 receives electronic communicationsaddressed to the user and initiated by multiple, different senders. Thereceived electronic communications may include multiple, different typesof communications received over multiple, different communicationmediums. The received electronic communications may be electronic mailmessages, text or SMS messages, telephone calls, instant messages, orany other types of electronic messages.

The system 200 determines one or more types of the receivedcommunications (320). For example, the system 200 analyzes aspects ofthe received communications to determine one or more types of thereceived communications. In this example, the system 200 may analyze thereceived communications to extract sender identity from the receivedcommunications and, in some implementations, determine a group to whicha sender of a communication belongs. The system 200 also may analyzecontent included in the received communications to determine whether areceived communication includes content of a particular type (e.g., acommunication that is labeled as “Urgent” or a communication thatincludes a request). The system 200 further may determine a medium overwhich the communications were received (e.g., determine whether acommunication is an email message, a text or SMS message, an instantmessage, a voice telephone call, etc.).

In addition, the system 200 may determine whether a receivedcommunication is associated with a priority designation and, if so, thetype of priority designation (e.g., whether a received communication isa high priority communication or a low priority communication). Thesystem 200 may determine a position in an address line of the user for areceived communication. For instance, the system 200 may determinewhether a received communication was directly addressed to the user orwhether the received communication was merely copied to the user.

In some implementations, the system 200 may determine a location of areceived communication in a string of communications. In theseimplementations, the system 200 may determine whether the receivedcommunication is an original communication in a string (e.g., the firstcommunication of the string) or whether the received communication is areply communication in a string (e.g., a second or later communicationin a string). Further, the system 200 may determine and track specificlocation in the string for the received communication (e.g., first,second, third, fourth, fifth, etc.). The system 200 may track whether ornot the received communication was forwarded to the user and/or whatpoint in the string the user was added to the communication string.

In some examples, the system 200 may determine whether a receivedcommunication has other recipients and, if so, attributes of the otherrecipients. In these examples, the system 200 may determine a number ofother recipients and whether the other recipients are included with theuser in an email list or group or added by the sender individually. Thesystem 200 may determine which one or more recipients received thecommunication and whether one or more particular recipients received thecommunication (e.g., the user's assistant, etc.).

The system 200 may determine the device on which the user received orperceived the communication. The system 200 further may determine a sizeof the received communication. The size of the received communicationmay be determined in terms of data size (e.g., bytes) associated withthe received communication and may include only content of thecommunication or content and attachments to the communication. The sizeof the received communication may be determined in terms of the numberof words or length of an audio and/or video message.

In addition to the referenced types of communications, the system 200may track any type of communication a user may receive. For instance,the system 200 may track user response to communications that areconfidential or communications for which the sender address is masked orhidden.

In some implementations, the system 200 stores, in electronic storage,data tracking received communications and the determined one or moretypes of the received communications. In these implementations, thesystem 200 may maintain a communication log that tracks data identifyingreceived communications. Each time a communication is received, thesystem 200 may add a new entry in the communication log indicating thedate/time of receipt, the subject of the received communication, anidentifier for the received communication, and/or other informationidentifying the received communication. In addition, the system 200 mayassociate the determined one or more types of the received communicationwith the entry in the communication log. Accordingly, over time in theseimplementations, the system 200 generates a detailed communication logthat tracks communications received for the user and determined types ofthe received communications.

The system 200 monitors responses by the user to the receivedcommunications for the user (330). For example, the system 200 detectsuser responses to communications and, when the system 200 detects aresponse to a communication, the system 200 identifies the communicationto which the user has responded. In this example, after the system 200identifies the communication to which the user has responded, the system200 tracks and stores, in electronic storage, data indicating parametersof the response. For instance, the system 200 may store identifyinginformation for the communication in association with an indication thatthe user has responded to the communication. In addition, the system 200may determine and store more detailed information related to theresponse, such as date/time of the response, how long the user took torespond to the communication, etc. The system 200 may maintain aresponse log that tracks data for detected user responses tocommunications. The system 200 also may update the communication logdiscussed above to include data indicative of the response. Table 1below shows an example communication log entry:

TABLE 1 Message Re- Iden- Receipt Other Re- sponse tifier Time SenderMedium Priority Types sponse Time ID Date/ Sender Email/IM/ High . . .Yes/No Date/ Number Time Identity Text/SMS or Time of Low of Re- Receiptsponse

The system 200 determines response patterns of the user by communicationtype based on the monitoring (340). For example, the system 200 analyzestracked data for the received communications, the determined one or moretypes of the communications, and the monitored responses to the receivedcommunications and identifies response patterns for particularcommunication types or combinations of communication types. In thisexample, the system 200 may analyze data included in a communication log(e.g., as shown in Table 1) and/or a response log maintained by thesystem 200 over a period of time. The analyzed communication and/orresponse log includes comprehensive data related to past communicationsreceived by the user and how the user has responded to the pastcommunications.

In some implementations, the system 200 determines a response patternfor a particular type of communication received by the user in the past.In these implementations, the system 200 identifies and accesses datatracking receipt, for the user, of communications having the particulartype. The system 200 also identifies and accesses data trackingresponses, by the user, to the received communications having theparticular type. Using the tracked receipt data and the tracked responsedata, the system 200 identifies patterns of the user's past responsebehavior for communications having the particular type. For example, thesystem 200 may determine a total number of communications of theparticular type that the user has received and a number ofcommunications of the particular type to which the user has responded.In this example, the system 200 may divide the number of communicationsof the particular type to which the user has responded by the totalnumber of communications of the particular type that the user hasreceived and compute a percentage of communications of the particulartype to which the user has responded (e.g., a response rate).

In some examples, the system 200 determines response timing patterns ofthe user for communications of the particular type using the trackedreceipt data and the tracked response data. For instance, the system 200may identify each instance in the tracked response data where the userresponded to a communication of the particular type in the past. Foreach identified instance, the system 200 may, using the tracked receiptdata and the tracked response data, determine a receipt time of thecommunication and a response time for the communication. Using thereceipt time and the response time, the system 200 may compute adifference between the response time and the receipt time and, thereby,determine how long it took the user to respond to the communication.After determining how long it took the user to respond to each of thecommunications associated with the particular type, the system 200 maydetermine an average response time of the user for communications havingthe particular type by summing the determined differences and dividingthe summation result by the total number of communications having theparticular type to which the user responded.

In some implementations, the system 200 determines time of day/day ofweek/date response timing patterns of the user for communications of theparticular type using the tracked receipt data and the tracked responsedata. For instance, the system 200 may identify each instance in thetracked response data where the user responded to a communication of theparticular type in the past. For each identified instance, the system200 may, using the tracked response data, determine a time of day and aday of the week when the user responded to the communication. Using thedetermined time of day and day of the week, the system 200 may identifytime of day and day of week response patterns of the user forcommunications of the particular type. For example, the system 200 maydetermine that 90% of the user's past responses to communications of theparticular type have occurred between the hours of 10 PM to 11 PM. Inthis example, the system 200 determines that the user typically respondsto communications of the particular type between the hours of 10 PM to11 PM. In another example, the system 200 may determine that 42% of theuser's past responses to communications of the particular type haveoccurred on Saturday and that 38% of the user's past responses tocommunications of the particular type have occurred on Sunday. In thisexample, system 200 determines that the user typically responds tocommunications of the particular type over the weekend (e.g., onSaturday or Sunday). Other types of time of day/day of week/dateresponse timing patterns may be determined.

The system 200 may update the response pattern data periodically or eachtime the user responds to a new communication. In some examples, thesystem 200 keeps running totals of communication information (e.g.,total number of received communication having the particular type) andupdates the response pattern data each time a new communication isreceived and/or each time a response communication is sent. Forinstance, the system 200 may maintain a running average response timefor communications of a particular type.

The system 200 stores, in electronic storage, response pattern data forthe user by communication type based on the determined response patterns(350). For instance, the system 200 may store the determined responsepattern data in a table or log that the system 200 may access and use insetting reminders to future communications. The response pattern datamay include a set of rules that indicate whether or not reminders shouldbe set for particular types of communications.

FIG. 4 illustrates an example data structure 400 that stores responsepattern data. The example data structure 400 may represent storedresponse pattern data as discussed above with respect to numeral 350.The example data structure 400 includes a type column 410 that stores adetermined type of a communication, a response rate column 420 thatstores a percentage of messages of the particular type to which the userhas responded in the past, a response time column 430 that stores anaverage response time of messages of the particular type to which theuser has responded in the past, and a date/time column 440 that stores adetermined time of day and/or day of week pattern of past responses bythe user to communications of the particular type.

The example data structure 400 includes a row 450 that stores responsepattern data for a particular sender, a row 452 that stores responsepattern data for a particular group of senders, and a row 454 thatstores response pattern data for particular content in a communication.The example data structure 400 also includes a row 456 that storesresponse pattern data for a particular medium of communication, a row458 that stores response pattern data for a particular prioritydesignation of communications, and a row 460 that stores responsepattern data for a particular location in an address line. The exampledata structure 400 further includes a row 462 that stores responsepattern data for a particular position in a message string, a row 464that stores response pattern data for particular other recipients of acommunication, a row 466 that stores response pattern data for aparticular device the user is using to perceive a communication, and arow 468 that stores response pattern data for a particular size of acommunication. Although the example data structure 400 is shown ashaving ten rows and four columns for ease of explanation, the exampledata structure 400 may include many more rows and many more columns.

FIG. 5 illustrates an example of a process 500 for automatically settinga response reminder time for a received communication. The system 200receives a communication for a user (510). For instance, the system 200receives an electronic communication addressed to the user and initiatedby a particular sender. The received electronic communication may beassociated with multiple, different types. The received electroniccommunication may be an electronic mail message, a text or SMS message,a telephone call, an instant message, or any other type of electronicmessage.

The system 200 determines a type of the received communication (520).For example, the system 200 analyzes aspects of the receivedcommunication to determine one or more types of the receivedcommunication. The system 200 may determine the one or more types of thereceived communication using techniques similar to those discussed abovewith respect to reference numeral 320.

The system 200 accesses, from electronic storage, response pattern dataassociated with the determined type of the received communication (530).For example, the system 200 accesses response pattern data stored inoperations described above with respect to reference numeral 350. Inthis example, the system 200 may access the response pattern data 400shown in FIG. 4 or data that is similar to the response pattern data 400shown in FIG. 4. The system 200 may identify a portion of the responsepattern data that is associated with the determined type of the receivedcommunication and access only the identified portion of the responsepattern data or extract the identified portion of the response patterndata from a larger amount (e.g., all) of the response pattern data thatis accessed.

The system 200 automatically, without human intervention, sets aresponse reminder time for the received communication based on theaccessed response pattern data associated with the determined type ofthe received communication (540). In some implementations, the system200 determines an anticipated or typical response time for thedetermined type of the received communication based on the user's pastresponse patterns. For example, the system 200 determines theanticipated or typical response time using an average response time(e.g., an average time between the user receiving or perceiving acommunication to a time when the user responds to the communication) forpast communications of the particular type to which the user hasresponded. In this example, the system 200 accesses or determines theaverage response time for past communications of the particular typebased on the response pattern data. The system 200 then sets theresponse reminder time by determining a time of receipt or perception ofthe received communication, adding the average response time to thedetermined time of receipt or perception, and automatically setting theresponse reminder time as a result of adding the average response timeto the determined time of receipt or perception.

In another example, the system 200 determines the anticipated or typicalresponse time using a time of day and/or day of week pattern of pastresponses by the user to communications of the particular type. In thisexample, if the system 200 determines that the user typically respondsto communications of the particular type between the hours of 10 PM to11 PM on Monday through Thursday, the system 200 determines ananticipated or typical response time that corresponds to this responsepattern. For instance, when the communication is received on a Wednesdayat 2 PM, the system 200 may automatically set the response reminder timefor Wednesday at 10 PM. When the communication is received on a Saturdayat 10 AM, the system 200 may automatically set the response remindertime for Monday at 10 PM.

In some examples, the system 200 may set the response reminder before adetermined anticipated or typical response time to provide a reminder touser at a time when the user still has time to generate and send aresponse by the determined anticipated or typical response time. Inthese examples, the system 200 may automatically set the responsereminder time for fifteen minutes or one hour prior to the determinedanticipated or typical response time and periodically provide remindersto the user after the automatically set response reminder time.

FIGS. 6-15 illustrate examples of setting a response reminder time basedon accessed response pattern data associated with a determined type of areceived communication. In addition, FIG. 16 illustrates a process 1600for determining a response reminder time for a received communicationbased on response pattern data. The response reminder time determinedusing the process 1600 may be the automatically set response remindertime.

FIG. 6 illustrates an example 600 of setting a reminder based on asender of a communication. As shown, the example 600 includes trackedresponse pattern data that has a sender column 610 and an averageresponse time column 620. The sender column 610 includes dataidentifying senders of communications to which a user has responded inthe past. The average response time column 620 includes data indicatingan average response time of the user for past communications receivedfrom the corresponding sender in the sender column 610. In the example600, the tracked response pattern data includes a first row 630indicating that the user responds to communications sent from Sender 1on average in one and a half hours. The tracked response pattern dataalso includes a second row 640 indicating that the user responds tocommunications sent from Sender 2 on average in one hour. Although thetracked response pattern data includes two rows for ease of explanation,the tracked response pattern data may include more rows and datacorresponding to many different senders.

In one example, the system 200 receives a first communication 650 sentby Sender 1. In this example, because the first communication 650 wasreceived on Jun. 6, 2009 at 4:35 PM and the user responds tocommunications sent from Sender 1 on average in one and a half hours,the system 200 provides a reminder 660 related to the firstcommunication 650 to the user on Jun. 6, 2009 at 6:05 PM. The reminder660 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the first communication to which the reminder corresponds, arespond interface control 662, and a modify interface control 664. Therespond interface control 662 enables the user to respond to the firstcommunication 650 (e.g., by displaying a response communicationinterface, such as a response email composition interface that resultswhen a user selects a respond control) when the user selects the respondinterface control 662 (e.g., using a mouse to select the respondinterface control 662). The modify interface control 664 enables theuser to modify the reminder 660 (e.g., by displaying a modify reminderinterface) when the user selects the modify interface control 664 (e.g.,using a mouse to select the modify interface control 664). For instance,the user may use a modify reminder interface to extend the reminder timeassociated with the reminder 660 (e.g., snooze the reminder 660) or tocancel the reminder 660. Other examples may provide a differentcombination (e.g., a subset) of the information provided in the reminder660 or other information that effectuates a reminder to the user.

In another example, the system 200 receives a second communication 670sent by Sender 2. In this example, because the second communication 670was received on Jun. 6, 2009 at 5:00 PM and the user responds tocommunications sent from Sender 2 on average in one hour, the system 200provides a reminder 680 related to the second communication 670 to theuser on Jun. 6, 2009 at 6:00 PM. Although the first communication 650was received prior to the second communication 670, the reminder 680 isprovided to the user prior to the reminder 660 because the usertypically responds to communications sent by Sender 2 faster thancommunications sent by Sender 1. The reminder 680 includes a reminderportion that indicates that a response to the communication is overdue,a communication portion that provides details related to the secondcommunication to which the reminder corresponds, a respond interfacecontrol 682, and a modify interface control 684. The respond interfacecontrol 682 is similar to the respond interface control 662 and themodify interface control 684 is similar to the modify interface control664.

FIG. 7 illustrates an example 700 of setting a reminder based on asender group associated with a sender of a communication. As shown, theexample 700 includes tracked response pattern data that has a sendergroup column 710 and an average response time column 720. The sendergroup column 710 includes data identifying sender groups associated withsenders of communications to which a user has responded in the past. Theaverage response time column 720 includes data indicating an averageresponse time of the user for past communications received from thecorresponding sender group in the sender column 710. In the example 700,the tracked response pattern data includes a first row 730 indicatingthat the user responds to communications sent from a Coworkers Group onaverage in 30 minutes. The tracked response pattern data also includes asecond row 740 indicating that the user responds to communications sentfrom a Friends Group on average in two days. Although the trackedresponse pattern data includes two rows for ease of explanation, thetracked response pattern data may include more rows and datacorresponding to many different sender groups.

In one example, the system 200 receives a first communication 750 sentby a sender in the Friends Group. In this example, because the firstcommunication 750 was received on Jun. 4, 2009 at 4:35 PM and the userresponds to communications sent from senders in the Friends Group onaverage in two days, the system 200 provides a reminder 760 related tothe first communication 750 to the user on Jun. 6, 2009 at 4:35 PM. Thereminder 760 includes a reminder portion that indicates that a responseto the communication is overdue, a communication portion that providesdetails related to the first communication to which the remindercorresponds, a respond interface control 762, and a modify interfacecontrol 764. The respond interface control 762 enables the user torespond to the first communication 750 (e.g., by displaying a responsecommunication interface, such as a response email composition interfacethat results when a user selects a respond control) when the userselects the respond interface control 762 (e.g., using a mouse to selectthe respond interface control 762). The modify interface control 764enables the user to modify the reminder 760 (e.g., by displaying amodify reminder interface) when the user selects the modify interfacecontrol 764 (e.g., using a mouse to select the modify interface control764). For instance, the user may use a modify reminder interface toextend the reminder time associated with the reminder 760 (e.g., snoozethe reminder 760) or to cancel the reminder 760. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 760 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 770sent by a sender in the Coworkers Group. In this example, because thesecond communication 770 was received on Jun. 6, 2009 at 5:00 PM and theuser responds to communications sent from senders in the Coworkers Groupon average in 30 minutes, the system 200 provides a reminder 780 relatedto the second communication 770 to the user on Jun. 6, 2009 at 5:30 PM.The reminder 780 includes a reminder portion that indicates that aresponse to the communication is overdue, a communication portion thatprovides details related to the second communication to which thereminder corresponds, a respond interface control 782, and a modifyinterface control 784. The respond interface control 782 is similar tothe respond interface control 762 and the modify interface control 784is similar to the modify interface control 764.

FIG. 8 illustrates an example 800 of setting a reminder based on contentof a communication. As shown, the example 800 includes tracked responsepattern data that has a content column 810 and an average response timecolumn 820. The content column 810 includes data identifying content ofcommunications to which a user has responded in the past. The contentmay include frequently identified words or phrases included incommunications to which the user responds. The content also may bedefined by the user as words or phrases the user wishes to track. Theaverage response time column 820 includes data indicating an averageresponse time of the user for past communications having thecorresponding content in the content column 810.

In the example 800, the tracked response pattern data includes a firstrow 830 indicating that the user responds to communications having thecontent “Urgent” on average in 10 minutes. The tracked response patterndata also includes a second row 832 indicating that the user responds tocommunications having the content “Thanks” on average longer than athreshold. For instance, the user may not frequently respond to messagesthat only have the text “Thanks” and, therefore, the average responsetime of the user for messages including the text “Thanks” is relativelylong. Because the average response time is so long (e.g., greater than athreshold, such as one month), the system 200 determines not to setreminders for communications having the text “Thanks”

The system 200 also may consider the volume or frequency of messagesthat have the particular content (e.g., “Thanks”) when determiningwhether to provide reminders for messages having the particular content.For example, if the user receives messages having particular content(e.g., “Thanks”) at a high volume or very frequently and takes arelatively long time to respond to those messages, the system 200 maydetermine not to set reminders for messages having the particularcontent (e.g., “Thanks”) because the computational burden may be largerelative to the benefit provided to the user. In fact, the user mayprefer not to receive reminders in this situation because the number ofreminders would be large and often applicable to communications the userreceived a long time ago. However, if the user receives messages havingparticular content (e.g., “Thanks”) at a low volume or infrequently andtakes a relatively long time to respond to those messages, the system200 may determine to set reminders for messages having the particularcontent (e.g., “Thanks”) because the computational burden and burden onthe user may be relatively low. When the system 200 identifies thesetypes of situations, the system 200 may request input from the user toselect how the user wishes to handle reminders for the situation.

In addition, the tracked response pattern data includes a third row 834indicating that the user responds to communications having the content“Code X” on average in one hour. The tracked response pattern dataincludes a fourth row 836 indicating that the user responds tocommunications having the content “Request 1” based on the actualcontent included in the request. For example, when the system 200determines that content of a communication includes a request and a timeby which the communication requests action, the system 200 sets areminder for the communication that is tied to the time included in therequest. In this example, the system 200 may analyze content included inelectronic communications and identify requests, such as “Please respondby . . . ” or “The deadline is . . . ” After identifying such a request,the system 200 attempts to identify a time associated with the requestby scanning content adjacent or near the identified request. When thesystem 200 successfully identifies a time, the system 200 sets areminder that is tied to the request. For instance, when the system 200identifies the request “Please respond by 4 PM today,” the system 200may set a reminder based on the 4 PM requested response time and providea reminder at 3 PM today to enable the user to meet the requestedresponse deadline. Although the tracked response pattern data includesfour rows for ease of explanation, the tracked response pattern data mayinclude more rows and data corresponding to many different types ofcontent and locations of content (e.g., subject of email message, bodyof email message, etc.).

In one example, the system 200 receives a first communication 840including a request “Meeting on June 7 at 5 PM?” In this example, thesystem 200 analyzes the content of the first communication 840 andidentifies the request and time associated with the request. Because thefirst communication 840 requests a meeting on Jun. 7, 2009 at 5 PM, thesystem 200 provides a reminder 850 related to the first communication840 to the user on Jun. 6, 2009 at 5:00 PM. Providing the reminder 850one day prior to the requested meeting may allow ample time for the userto respond and accept the meeting if desired. The system 200 may set thereminder time based on type of request (e.g., a reminder for a requestfor a meeting may be set further in advance than a reminder for arequest for a response), the time period between receipt of thecommunication and the request time (e.g., a reminder may be set at amidpoint between time of receipt of communication and time associatedwith request), and/or input of the user as to when reminders should beprovided.

The reminder 850 includes a reminder portion that indicates that aresponse to the communication is overdue, a communication portion thatprovides details related to the first communication to which thereminder corresponds, a respond interface control, and a modifyinterface control.

In another example, the system 200 receives a second communication 860that includes the content “Urgent” in the subject line. In this example,the system 200 analyzes the content of the subject line of the secondcommunication 860, identifies the content “Urgent” in the subject line,and matches the content “Urgent” to the tracked response pattern data.Because the second communication 860 was received on Jun. 6, 2009 at4:45 PM and the user responds to communications having the content“Urgent” on average in 10 minutes, the system 200 provides a reminder870 related to the second communication 860 to the user on Jun. 6, 2009at 4:55 PM. The reminder 870 includes a reminder portion that indicatesthat a response to the communication is overdue, a communication portionthat provides details related to the second communication to which thereminder corresponds, a respond interface control, and a modifyinterface control.

In yet another example, the system 200 receives a third communication880 that includes the content “Code X” in the body of the message. Inthis example, the system 200 analyzes the content of the body of thethird communication 880, identifies the content “Code X” in the body ofthe message, and matches the content “Code X” to the tracked responsepattern data. Because the third communication 880 was received on Jun.6, 2009 at 5:00 PM and the user responds to communications having thecontent “Code X” on average in one hour, the system 200 provides areminder 890 related to the third communication 880 to the user on Jun.6, 2009 at 6:00 PM. The reminder 890 includes a reminder portion thatindicates that a response to the communication is overdue, acommunication portion that provides details related to the secondcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

FIG. 9 illustrates an example 900 of setting a reminder based on acommunication medium. As shown, the example 900 includes trackedresponse pattern data that has a medium column 910 and an averageresponse time column 920. The medium column 910 includes dataidentifying a medium of communications to which a user has responded inthe past. The medium may include email, instant message, telephone, textor SMS message, etc. The average response time column 920 includes dataindicating an average response time of the user for past communicationshaving the corresponding medium in the medium column 910.

In the example 900, the tracked response pattern data includes a firstrow 930 indicating that the user responds to email communications onaverage in one hour. The tracked response pattern data also includes asecond row 932 indicating that the user responds to instant messagecommunications on average in two minutes. In addition, the trackedresponse pattern data includes a third row 934 indicating that the userresponds to SMS/text communications on average in five minutes. Althoughthe tracked response pattern data includes three rows for ease ofexplanation, the tracked response pattern data may include more rows anddata corresponding to additional types of communications (e.g.,telephone calls, etc.).

In one example, the system 200 receives a first communication 940 overthe email medium. In this example, the system 200 determines that thefirst communication 940 is an email communication, identifies the row930 in the tracked response pattern data corresponding to emailcommunications, and accesses the average response time data from the row930 in the tracked response pattern data. Because the firstcommunication 940 was received on Jun. 6, 2009 at 4:35 PM and the userresponds to email communications on average in one hour, the system 200provides a reminder 950 related to the first communication 940 to theuser on Jun. 6, 2009 at 5:35 PM. The reminder 950 includes a reminderportion that indicates that a response to the communication is overdue,a communication portion that provides details related to the firstcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

In another example, the system 200 receives a second communication 960over the instant message medium. In this example, the system 200determines that the second communication 960 is an instant messagecommunication, identifies the row 932 in the tracked response patterndata corresponding to instant message communications, and accesses theaverage response time data from the row 932 in the tracked responsepattern data. Because the second communication 960 was received on Jun.6, 2009 at 4:35 PM and the user responds to instant messagecommunications on average in two minutes, the system 200 provides areminder 970 related to the second communication 960 to the user on Jun.6, 2009 at 4:37 PM. The reminder 970 includes a reminder portion thatindicates that a response to the communication is overdue, acommunication portion that provides details related to the secondcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

In yet another example, the system 200 receives a third communication980 over the text or SMS medium. In this example, the system 200determines that the third communication 980 is a text or SMScommunication, identifies the row 934 in the tracked response patterndata corresponding to text or SMS communications, and accesses theaverage response time data from the row 934 in the tracked responsepattern data. Because the third communication 980 was received on Jun.6, 2009 at 4:35 PM and the user responds to text or SMS communicationson average in five minutes, the system 200 provides a reminder 990related to the third communication 980 to the user on Jun. 6, 2009 at4:40 PM. The reminder 990 includes a reminder portion that indicatesthat a response to the communication is overdue, a communication portionthat provides details related to the third communication to which thereminder corresponds, a respond interface control, and a modifyinterface control.

FIG. 10 illustrates an example 1000 of setting a reminder based on apriority designation of a communication. As shown, the example 1000includes tracked response pattern data that has a priority designationcolumn 1010 and an average response time column 1020. The prioritydesignation column 1010 includes data identifying a priority designationof communications to which a user has responded in the past. The averageresponse time column 1020 includes data indicating an average responsetime of the user for past communications received having thecorresponding priority designation in the priority designation column1010. In the example 1000, the tracked response pattern data includes afirst row 1030 indicating that the user responds to communicationshaving a priority designation of High on average in 15 minutes. Thetracked response pattern data also includes a second row 1040 indicatingthat the user responds to communications having a priority designationof Low on average in two hours. Although the tracked response patterndata includes two rows for ease of explanation, the tracked responsepattern data may include more rows and data corresponding to manydifferent priority designations.

In one example, the system 200 receives a first communication 1050having a priority designation of High. In this example, because thefirst communication 1050 has a priority designation of High, wasreceived on Jun. 6, 2009 at 4:35 PM, and the user responds tocommunications having a priority designation of High on average in 15minutes, the system 200 provides a reminder 1060 related to the firstcommunication 1050 to the user on Jun. 6, 2009 at 4:50 PM. The reminder1060 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the first communication to which the reminder corresponds, arespond interface control 1062, and a modify interface control 1064. Therespond interface control 1062 enables the user to respond to the firstcommunication 1050 (e.g., by displaying a response communicationinterface, such as a response email composition interface that resultswhen a user selects a respond control) when the user selects the respondinterface control 1062 (e.g., using a mouse to select the respondinterface control 1062). The modify interface control 1064 enables theuser to modify the reminder 1060 (e.g., by displaying a modify reminderinterface) when the user selects the modify interface control 1064(e.g., using a mouse to select the modify interface control 1064). Forinstance, the user may use a modify reminder interface to extend thereminder time associated with the reminder 1060 (e.g., snooze thereminder 1060) or to cancel the reminder 1060. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 1060 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 1070having a priority designation of Low. In this example, because thesecond communication 1070 has a priority designation of Low, wasreceived on Jun. 6, 2009 at 3:00 PM, and the user responds tocommunications having a priority designation of Low on average in twohours, the system 200 provides a reminder 1080 related to the secondcommunication 1070 to the user on Jun. 6, 2009 at 5:00 PM. The reminder1080 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the second communication to which the reminder corresponds, arespond interface control 1082, and a modify interface control 1084. Therespond interface control 1082 is similar to the respond interfacecontrol 1062 and the modify interface control 1084 is similar to themodify interface control 1064.

FIG. 11 illustrates an example 1100 of setting a reminder based on anaddress line of a communication. As shown, the example 1100 includestracked response pattern data that has an address line column 1110 andan average response time column 1120. The address line column 1110includes data identifying a location in an address line ofcommunications to which a user has responded in the past. For instance,the location in the address line may indicate whether the communicationdirectly sent to the user (e.g., the TO portion of an address line) orwhether the user was only copied on the communication (e.g., the CCportion of an address line). The average response time column 1120includes data indicating an average response time of the user for pastcommunications received having the corresponding address line in theaddress line column 1110. In the example 1100, the tracked responsepattern data includes a first row 1130 indicating that the user respondsto communications directly addressed to the user (e.g., the user islisted in the TO field of the address) on average in two hours. Thetracked response pattern data also includes a second row 1140 indicatingthat the user responds to communications on which the user was copied(e.g., the user is listed in the CC field of the address) on average inone day. Although the tracked response pattern data includes two rowsfor ease of explanation, the tracked response pattern data may includemore rows and data corresponding to different address line options.

In one example, the system 200 receives a first communication 1150directly addressed to the user (e.g., the user is listed in the TO fieldof the address). In this example, because the first communication 1150was directly addressed to the user, was received on Jun. 6, 2009 at 4:35PM, and the user responds to direct address communications on average intwo hours, the system 200 provides a reminder 1160 related to the firstcommunication 1150 to the user on Jun. 6, 2009 at 6:35 PM. The reminder1160 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the first communication to which the reminder corresponds, arespond interface control 1162, and a modify interface control 1164. Therespond interface control 1162 enables the user to respond to the firstcommunication 1150 (e.g., by displaying a response communicationinterface, such as a response email composition interface that resultswhen a user selects a respond control) when the user selects the respondinterface control 1162 (e.g., using a mouse to select the respondinterface control 1162). The modify interface control 1164 enables theuser to modify the reminder 1160 (e.g., by displaying a modify reminderinterface) when the user selects the modify interface control 1164(e.g., using a mouse to select the modify interface control 1164). Forinstance, the user may use a modify reminder interface to extend thereminder time associated with the reminder 1160 (e.g., snooze thereminder 1160) or to cancel the reminder 1160. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 1160 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 1170on which the user was copied (e.g., the user is listed in the CC fieldof the address). In this example, because the second communication 1170was only copied to the user, was received on Jun. 6, 2009 at 3:00 PM,and the user responds to copied communications on average in one day,the system 200 provides a reminder 1180 related to the secondcommunication 1170 to the user on Jun. 7, 2009 at 3:00 PM. The reminder1180 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the second communication to which the reminder corresponds, arespond interface control 1182, and a modify interface control 1184. Therespond interface control 1182 is similar to the respond interfacecontrol 1162 and the modify interface control 1184 is similar to themodify interface control 1164.

FIG. 12 illustrates an example 1200 of setting a reminder based on astring history of a communication. As shown, the example 1200 includestracked response pattern data that has a string history column 1210 andan average response time column 1220. The string history column 1210includes data identifying a location in a string of communications towhich a user has responded in the past. For instance, the location inthe string may indicate whether the communication was an originalcommunication sent to the user (e.g., the first communication in astring of communications) or whether the communication was a reply to acommunication sent by the user (e.g., the second or later communicationin a string of communications). The average response time column 1220includes data indicating an average response time of the user for pastcommunications received having the corresponding string history in thestring history column 1210. In the example 1200, the tracked responsepattern data includes a first row 1230 indicating that the user respondsto original communications sent to the user on average in two hours. Thetracked response pattern data also includes a second row 1240 indicatingthat the user responds to reply communications on average in four hours.Although the tracked response pattern data includes two rows for ease ofexplanation, the tracked response pattern data may include more rows anddata corresponding to different string history options (e.g.,communications forwarded to the user, a reply to a communication notsent by the user, different numbers of communications in the string,etc.).

In one example, the system 200 receives a first communication 1250 thatis an original communication sent to the user. In this example, becausethe first communication 1250 was an original communication, was receivedon Jun. 6, 2009 at 4:35 PM, and the user responds to originalcommunications on average in two hours, the system 200 provides areminder 1260 related to the first communication 1250 to the user onJun. 6, 2009 at 6:35 PM. The reminder 1260 includes a reminder portionthat indicates that a response to the communication is overdue, acommunication portion that provides details related to the firstcommunication to which the reminder corresponds, a respond interfacecontrol 1262, and a modify interface control 1264. The respond interfacecontrol 1262 enables the user to respond to the first communication 1250(e.g., by displaying a response communication interface, such as aresponse email composition interface that results when a user selects arespond control) when the user selects the respond interface control1262 (e.g., using a mouse to select the respond interface control 1262).The modify interface control 1264 enables the user to modify thereminder 1260 (e.g., by displaying a modify reminder interface) when theuser selects the modify interface control 1264 (e.g., using a mouse toselect the modify interface control 1264). For instance, the user mayuse a modify reminder interface to extend the reminder time associatedwith the reminder 1260 (e.g., snooze the reminder 1260) or to cancel thereminder 1260. Other examples may provide a different combination (e.g.,a subset) of the information provided in the reminder 1260 or otherinformation that effectuates a reminder to the user.

In another example, the system 200 receives a second communication 1270that is a reply to a communication sent by the user. In this example,because the second communication 1270 is a reply communication, wasreceived on Jun. 6, 2009 at 5:35 PM, and the user responds to replycommunications on average in four hours, the system 200 provides areminder 1280 related to the second communication 1270 to the user onJun. 6, 2009 at 9:35 PM. The reminder 1280 includes a reminder portionthat indicates that a response to the communication is overdue, acommunication portion that provides details related to the secondcommunication to which the reminder corresponds, a respond interfacecontrol 1282, and a modify interface control 1284. The respond interfacecontrol 1282 is similar to the respond interface control 1262 and themodify interface control 1284 is similar to the modify interface control1264.

FIG. 13 illustrates an example 1300 of setting a reminder based on anarrangement within a recipient list. As shown, the example 1300 includestracked response pattern data that has a recipient list column 1310 andan average response time column 1320. The recipient list column 1310includes data identifying recipient list arrangement for communicationsto which a user has responded in the past. The recipient listarrangement may include sent to the user only, sent to the user and atleast one other user, sent to the user and another particular user, etc.The average response time column 1320 includes data indicating anaverage response time of the user for past communications having thecorresponding recipient list arrangement in the recipient list column1310.

In the example 1300, the tracked response pattern data includes a firstrow 1330 indicating that the user responds to communications sent onlyto User A on average in one hour. The tracked response pattern data alsoincludes a second row 1332 indicating that the user responds tocommunications sent to User A and one or more other users on average intwo hours. In addition, the tracked response pattern data includes athird row 1334 indicating that the user responds to communications sentto User A and User B on average in five days. Although the trackedresponse pattern data includes three rows for ease of explanation, thetracked response pattern data may include more rows and datacorresponding to additional recipient list arrangements ofcommunications.

In one example, the system 200 receives a first communication 1340 sentonly to User A. In this example, the system 200 determines that thefirst communication 1340 is sent only to User A, identifies the row 1330in the tracked response pattern data corresponding to communicationssent only to User A, and accesses the average response time data fromthe row 1330 in the tracked response pattern data. Because the firstcommunication 1340 was received on Jun. 6, 2009 at 4:35 PM and the userresponds to communications sent only to User A on average in one hour,the system 200 provides a reminder 1350 related to the firstcommunication 1340 to the user on Jun. 6, 2009 at 5:35 PM. The reminder1350 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the first communication to which the reminder corresponds, arespond interface control, and a modify interface control.

In another example, the system 200 receives a second communication 1360that is sent to User A and others. In this example, the system 200determines that the second communication 1360 is sent to User A andothers, identifies the row 1332 in the tracked response pattern datacorresponding to communications sent to User A and others, and accessesthe average response time data from the row 1332 in the tracked responsepattern data. Because the second communication 1360 was received on Jun.6, 2009 at 4:35 PM and the user responds to communications sent to UserA and others on average in two hours, the system 200 provides a reminder1370 related to the second communication 1360 to the user on Jun. 6,2009 at 6:35 PM. The reminder 1370 includes a reminder portion thatindicates that a response to the communication is overdue, acommunication portion that provides details related to the secondcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

In yet another example, the system 200 receives a third communication1380 that is sent to User A and User B. In this example, the system 200determines that the third communication 1380 is sent to User A and UserB, identifies the row 1334 in the tracked response pattern datacorresponding to communications sent to User A and User B, and accessesthe average response time data from the row 1334 in the tracked responsepattern data. Because the third communication 1380 was received on Jun.6, 2009 at 4:35 PM and the user responds to communications sent to UserA and User B on average in five days, the system 200 provides a reminder1390 related to the third communication 1380 to the user on Jun. 11,2009 at 4:35 PM. The reminder 1390 includes a reminder portion thatindicates that a response to the communication is overdue, acommunication portion that provides details related to the thirdcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

FIG. 14 illustrates an example 1400 of setting a reminder based on adevice the user is using to receive or perceive a communication. Asshown, the example 1400 includes tracked response pattern data that hasa device column 1410 and an average response time column 1420. Thedevice column 1410 includes data identifying a device a user has used inthe past to receive or perceive communications. The average responsetime column 1420 includes data indicating an average response time ofthe user for past communications having the corresponding device in thedevice column 1410. In the example 1400, the tracked response patterndata includes a first row 1430 indicating that the user responds tocommunications received or perceived on a personal computer (PC) onaverage in ten minutes. The tracked response pattern data also includesa second row 1440 indicating that the user responds to communicationsreceived or perceived on a smart phone on average in four hours.Although the tracked response pattern data includes two rows for ease ofexplanation, the tracked response pattern data may include more rows anddata corresponding to different device options.

In one example, the system 200 receives a first communication 1450 thatis received or perceived on a PC. In this example, because the firstcommunication 1450 was received or perceived on the PC, was received onJun. 6, 2009 at 4:35 PM, and the user responds to communications on thePC on average in ten minutes, the system 200 provides a reminder 1460related to the first communication 1450 to the user on Jun. 6, 2009 at4:45 PM. The reminder 1460 includes a reminder portion that indicatesthat a response to the communication is overdue, a communication portionthat provides details related to the first communication to which thereminder corresponds, a respond interface control 1462, and a modifyinterface control 1464. The respond interface control 1462 enables theuser to respond to the first communication 1450 (e.g., by displaying aresponse communication interface, such as a response email compositioninterface that results when a user selects a respond control) when theuser selects the respond interface control 1462 (e.g., using a mouse toselect the respond interface control 1462). The modify interface control1464 enables the user to modify the reminder 1460 (e.g., by displaying amodify reminder interface) when the user selects the modify interfacecontrol 1464 (e.g., using a mouse to select the modify interface control1464). For instance, the user may use a modify reminder interface toextend the reminder time associated with the reminder 1460 (e.g., snoozethe reminder 1460) or to cancel the reminder 1460. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 1460 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 1470that is received or perceived on a smart phone. In this example, becausethe second communication 1470 was received or perceived on the smartphone, was received on Jun. 6, 2009 at 4:35 PM, and the user responds tocommunications on the smart phone on average in four hours, the system200 provides a reminder 1480 related to the second communication 1470 tothe user on Jun. 6, 2009 at 8:35 PM. The reminder 1480 includes areminder portion that indicates that a response to the communication isoverdue, a communication portion that provides details related to thesecond communication to which the reminder corresponds, a respondinterface control 1482, and a modify interface control 1484. The respondinterface control 1482 is similar to the respond interface control 1462and the modify interface control 1484 is similar to the modify interfacecontrol 1464.

FIG. 15 illustrates an example 1500 of setting a reminder based on asize of a communication. As shown, the example 1500 includes trackedresponse pattern data that has a size column 1510 and an averageresponse time column 1520. The size column 1510 includes dataidentifying a size of communications to which a user has responded inthe past. The average response time column 1520 includes data indicatingan average response time of the user for past communications having thecorresponding size in the size column 1510. In the example 1500, thetracked response pattern data includes a first row 1530 indicating thatthe user responds to communications having a size of greater than 500words on average in two hours. The tracked response pattern data alsoincludes a second row 1540 indicating that the user responds tocommunications having a size of less than 500 words on average in 15minutes. Although the tracked response pattern data includes two rowsfor ease of explanation, the tracked response pattern data may includemore rows and data corresponding to many different size options.

In one example, the system 200 receives a first communication 1550having more than 500 words of text. In this example, because the firstcommunication 1550 has more than 500 words of text, was received on Jun.6, 2009 at 4:35 PM, and the user responds to communications having morethan 500 words of text on average in two hours, the system 200 providesa reminder 1560 related to the first communication 1550 to the user onJun. 6, 2009 at 6:35 PM. The reminder 1560 includes a reminder portionthat indicates that a response to the communication is overdue, acommunication portion that provides details related to the firstcommunication to which the reminder corresponds, a respond interfacecontrol 1562, and a modify interface control 1564. The respond interfacecontrol 1562 enables the user to respond to the first communication 1550(e.g., by displaying a response communication interface, such as aresponse email composition interface that results when a user selects arespond control) when the user selects the respond interface control1562 (e.g., using a mouse to select the respond interface control 1562).The modify interface control 1564 enables the user to modify thereminder 1560 (e.g., by displaying a modify reminder interface) when theuser selects the modify interface control 1564 (e.g., using a mouse toselect the modify interface control 1564). For instance, the user mayuse a modify reminder interface to extend the reminder time associatedwith the reminder 1560 (e.g., snooze the reminder 1560) or to cancel thereminder 1560. Other examples may provide a different combination (e.g.,a subset) of the information provided in the reminder 1560 or otherinformation that effectuates a reminder to the user.

In another example, the system 200 receives a second communication 1570that has less than 500 words of text. In this example, because thesecond communication 1570 has less than 500 words of text, was receivedon Jun. 6, 2009 at 5:35 PM, and the user responds to communicationshaving less than 500 words of text on average in 15 minutes, the system200 provides a reminder 1580 related to the second communication 1570 tothe user on Jun. 6, 2009 at 5:50 PM. The reminder 1580 includes areminder portion that indicates that a response to the communication isoverdue, a communication portion that provides details related to thesecond communication to which the reminder corresponds, a respondinterface control 1582, and a modify interface control 1584. The respondinterface control 1582 is similar to the respond interface control 1562and the modify interface control 1584 is similar to the modify interfacecontrol 1564.

FIG. 16 illustrates an example of a process 1600 for determining aresponse reminder time for a received communication. The system 200identifies a day and/or time of day response pattern associated with thedetermined type of the received communication based on the accessedresponse pattern data (1610). For instance, the system 200 accesses theday and/or time of day response pattern from stored response patterndata (e.g., from the data structure 400). The day and/or time of dayresponse pattern may have been determined by monitoring responses tocommunications of the determined type and identifying a day and/or timeof day the user typically (e.g., more than 50% of the time) hasresponded to the communications of the determined type in the past. Theday and/or time of day may indicate a particular day of the week, arange of multiple days of the week, particular calendar dates or timeperiods (e.g., months), a particular time of day, and/or a particularrange of times of the day. The time of day or time of day range may varyfor different days of the week or different time periods.

The system 200 identifies a relative response time pattern associatedwith the determined type of the received communication based on theaccessed response pattern data, the relative response time pattern beingrelative to time of receipt of a communication (1620). For instance, thesystem 200 accesses the relative response time pattern from storedresponse pattern data (e.g., from the data structure 400). The relativeresponse time pattern may have been determined by monitoring responsesto communications of the determined type and identifying a time relativeto receipt or perception by which the user has typically (e.g., morethan 50% of the time) responded to the communications of the determinedtype in the past. The relative response time pattern may be an averageresponse time, a median response time, etc.

The system 200 determines a response reminder time for the receivedcommunication based on the identified day and/or time of day responsepattern and/or the identified relative response time pattern (1630). Forexample, the system 200 accounts for both the identified day and/or timeof day response pattern and/or the identified relative response timepattern. In this example, the system 200 may attempt to determine aresponse reminder time that corresponds to both the identified dayand/or time of day response pattern and the identified relative responsetime pattern. The system 200 may determine the relative responsereminder time and then compare the determined relative response remindertime to the day and/or time of day response pattern. When the relativeresponse reminder time corresponds to the day and/or time of dayresponse pattern, the system 200 sets the response reminder time for thereceived communication as the time matching both patterns. When therelative response reminder time does not correspond to the day and/ortime of day response pattern, the system 200 evaluates other options forsetting the response reminder time.

In some implementations, the system 200 determines a difference betweena computed relative reminder time and the day and/or time of dayresponse pattern and compares the difference to a threshold. When thecomparison reveals that the difference is within the threshold, thesystem 200 determines to use the computed relative reminder time as theresponse reminder time or determines to adjust the computed relativereminder time to match the day and/or time of day response pattern. Whenthe comparison reveals that the difference is outside of the threshold,the system 200 determines to compute, based on both the computedrelative reminder time and the day and/or time of day response pattern,another reminder time that does not match the computed relative remindertime or the day and/or time of day response pattern.

For instance, the system 200 may determine a midpoint between thecomputed relative reminder time and the day and/or time of day responsepattern and set the response reminder time as the determined midpoint.As one example, when the relative reminder time is 1 PM and the time ofday range starts at 5 PM, the system 200 may set the response remindertime at the 3 PM midpoint between 1 PM and 5 PM. The system 200 mayadjust the computed relative reminder time forward or backward in timeto account for the day and/or time of day response pattern.

In the example 1700, the tracked response pattern data includes a firstrow 1732 indicating that the user responds to communications sent bySender 1 on average in three hours and typically Monday through Fridaybetween the hours of 10 PM to 11 PM. The tracked response pattern dataalso includes a second row 1734 indicating that the user responds tocommunications sent by Sender 2 on average in three days and typicallyon Saturday or Sunday. In addition, the tracked response pattern dataincludes a third row 1736 indicating that the user responds tocommunications sent by Sender 3 on average in two hours and typicallybetween the hours of 8 AM to 12 PM. Although the tracked responsepattern data includes three rows for ease of explanation, the trackedresponse pattern data may include more rows and data corresponding toadditional senders of communications (or other types of communicationsdescribed throughout).

In one example, the system 200 receives a first communication 1740 sentby Sender 1. In this example, the system 200 determines that the firstcommunication 1740 is sent by Sender 1, identifies the row 1732 in thetracked response pattern data corresponding to communications sent bySender 1, and accesses the relative response time and the time ofday/day of week response pattern data from the row 1732 in the trackedresponse pattern data. The system 200 automatically, without humanintervention, determines a response reminder time for the firstcommunication 1740 based on a combination of the accessed relativeresponse time and time of day/day of week response pattern data. Becausethe first communication 1740 was received on Jun. 4, 2009 at 4:35 PM andthe user responds to communications sent by Sender 1 on average in threehours and typically Monday through Friday between the hours of 10 PM to11 PM, the system 200 provides a reminder 1750 related to the firstcommunication 1740 to the user on Jun. 4, 2009 at 10:00 PM. The system200 determines the Jun. 4, 2009 at 10:00 PM reminder time using acombination of the accessed relative response time and time of day/dayof week response pattern data. For instance, the system 200 determinesthat a relative reminder time should be set as Jun. 4, 2009 at 6:35 PMbased solely on the relative response time. The system 200 compares therelative reminder time (Jun. 4, 2009 at 6:35 PM) to the time of day/dayof week response pattern data. When the relative reminder time matchesthe time of day/day of week response pattern data, the response reminderis set as the relative reminder time. When the relative reminder timedoes not match the time of day/day of week response pattern data, theresponse reminder is set as the relative reminder time adjusted based onthe time of day/day of week response pattern data. For example, thesystem 200 adjusts the relative reminder time to correspond to theclosest time included in the time of day/day of week response pattern.In this example, the system 200 determines that, although the relativereminder time falls within the day of week response pattern (e.g.,Monday through Friday), the relative reminder time does not fall withinthe time of day response pattern (e.g., 10 PM to 11 PM). Accordingly, inthis example, the system 200 adjusts the relative reminder time (Jun. 4,2009 at 6:35 PM) to the closest time that corresponds to the time of dayresponse pattern (Jun. 4, 2009 at 10:00 PM). The reminder 1750 includesa reminder portion that indicates that a response to the communicationis overdue, a communication portion that provides details related to thefirst communication to which the reminder corresponds, a respondinterface control, and a modify interface control.

In another example, the system 200 receives a second communication 1760that is sent by Sender 2. In this example, the system 200 determinesthat the second communication 1760 is sent by Sender 2, identifies therow 1734 in the tracked response pattern data corresponding tocommunications sent by Sender 2, and accesses the relative response timeand the time of day/day of week response pattern data from the row 1734in the tracked response pattern data. The system 200 automatically,without human intervention, determines a response reminder time for thesecond communication 1760 based on a combination of the accessedrelative response time and time of day/day of week response patterndata. Because the second communication 1760 was received on Jun. 6, 2009at 4:45 PM and the user responds to communications sent by Sender 2 onaverage in three days and typically on Saturday or Sunday, the system200 provides a reminder 1770 related to the second communication 1760 tothe user on Jun. 7, 2009 at 4:45 PM. The system 200 determines the Jun.7, 2009 at 4:45 PM reminder time using a combination of the accessedrelative response time and time of day/day of week response patterndata. For instance, the system 200 determines that a relative remindertime should be set as Jun. 9, 2009 at 4:45 PM based solely on therelative response time. The system 200 compares the relative remindertime (Jun. 9, 2009 at 4:45 PM) to the time of day/day of week responsepattern data. When the relative reminder time matches the time ofday/day of week response pattern data, the response reminder is set asthe relative reminder time. When the relative reminder time does notmatch the time of day/day of week response pattern data, the responsereminder is set as the relative reminder time adjusted based on the timeof day/day of week response pattern data. For example, the system 200adjusts the relative reminder time to correspond to a time included inthe time of day/day of week response pattern. In this example, thesystem 200 determines that the relative reminder time does not fallwithin the day of week response pattern because Jun. 9, 2009 is aTuesday. Accordingly, in this example, the system 200 adjusts a day ofthe relative reminder time (Jun. 9, 2009 at 4:45 PM) to the closest dayof week that corresponds to the day of week response pattern (Jun. 7,2009 at 4:45 PM). Although earlier, the system 200 determines that therelative reminder day (Jun. 9, 2009) is closer to Sunday, Jun. 7, 2009than the next closest option of Saturday, Jun. 13, 2009. The system 200maintains a time of day of the relative reminder time because the row1734 does not include time of day response pattern data. The reminder1770 includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the second communication to which the reminder corresponds, arespond interface control, and a modify interface control.

In yet another example, the system 200 receives a third communication1780 that is sent by Sender 3. In this example, the system 200determines that the third communication 1780 is sent by Sender 3,identifies the row 1736 in the tracked response pattern datacorresponding to communications sent by Sender 3, and accesses therelative response time and the time of day/day of week response patterndata from the row 1736 in the tracked response pattern data. The system200 automatically, without human intervention, determines a responsereminder time for the third communication 1780 based on a combination ofthe accessed relative response time and time of day/day of week responsepattern data. Because the third communication 1780 was received on Jun.6, 2009 at 5:00 PM and the user responds to communications sent bySender 3 on average in two hours and typically between the hours of 8 AMto 12 PM, the system 200 provides a reminder 1790 related to the thirdcommunication 1780 to the user on Jun. 7, 2009 at 8:00 AM. The system200 determines the Jun. 7, 2009 at 8:00 AM reminder time using acombination of the accessed relative response time and time of day/dayof week response pattern data. For instance, the system 200 determinesthat a relative reminder time should be set as Jun. 6, 2009 at 7:00 PMbased solely on the relative response time. The system 200 compares therelative reminder time (Jun. 6, 2009 at 7:00 PM) to the time of day/dayof week response pattern data. When the relative reminder time matchesthe time of day/day of week response pattern data, the response reminderis set as the relative reminder time. When the relative reminder timedoes not match the time of day/day of week response pattern data, theresponse reminder is set as the relative reminder time adjusted based onthe time of day/day of week response pattern data. For example, thesystem 200 adjusts the relative reminder time to correspond to a timeincluded in the time of day/day of week response pattern. In thisexample, the system 200 determines that the relative reminder time (7:00PM) does not fall within the time of day response pattern (8 AM to 12PM). Accordingly, in this example, the system 200 adjusts the relativereminder time (Jun. 6, 2009 at 7:00 PM) to the next time thatcorresponds to the time of day response pattern (Jun. 7, 2009 at 8:00AM). Although the relative reminder time is closer to 12:00 PM on Jun.6, 2009, the system 200 determines not to adjust the reminder to 12:00PM on Jun. 6, 2009 because that time had passed when the thirdcommunication 1780 was received. Accordingly, the system 200 sets thereminder to the next time in the future that corresponds to the time ofday response pattern. The reminder 1790 includes a reminder portion thatindicates that a response to the communication is overdue, acommunication portion that provides details related to the thirdcommunication to which the reminder corresponds, a respond interfacecontrol, and a modify interface control.

In some implementations, the system 200 may set, using a combination ofthe accessed relative response time and time of day/day of week responsepattern data, the response reminder time to a time that does notcorrespond to the time of day/day of week response pattern data. Inthese implementations, the system 200 may determine a relative remindertime based on the relative response time response pattern data and alsodetermine a time of day/day of week reminder time based on the time ofday/day of week response pattern data. Instead of adjusting the relativereminder time to a time that corresponds to the time of day/day of weekresponse pattern data, the system 200 may determine a response remindertime as an average of the relative reminder time and the time of day/dayof week reminder time even if the average reminder time does notcorrespond to the relative response time response pattern data or thetime of day/day of week response pattern data.

FIG. 18 illustrates an example of a process 1800 for determining whetherto set a response reminder for a received communication based onresponse rate data. The system 200 identifies response rate dataassociated with a determined type of the received communication based onaccessed response pattern data (1810). For instance, the system 200accesses the response rate data from stored response pattern data (e.g.,from the data structure 400). The response rate data may have beendetermined by monitoring receipt and responses to communications of thedetermined type and determining a percentage of communications of thedetermined type to which the user has responded. In someimplementations, the system 200 may maintain, in the response patterndata, a running total of communications that user has received of thedetermined type and a running total of responses the user has sent tocommunications of the determined type. In these implementations, toidentify the response rate data, the system 200 may access the runningtotal of received communications and the running total of responses andcompute a response rate based on the running total of receivedcommunications and the running total of responses (e.g., dividing therunning total of responses by the running total of receivedcommunications).

The system 200 compares the identified response rate data to a ratethreshold (1820). For instance, the system 200 accesses a rate threshold(e.g., 50%, 80%, etc.) from electronic storage and compares theidentified or determined response rate data to the rate threshold. Thesystem 200 may access a general rate threshold that applies to allcommunications or may access a specific rate threshold that applies toonly communications of the determined type. The rate threshold may bedefined based on user input.

In some implementations, the system 200 may define the rate threshold bytracking the user's reaction to set reminders in the past. In theseimplementations, the system 200 may determine whether the user cancelleda reminder or whether the user responded to a communication based on thereminder. The system 200 may track the circumstances and types ofcommunications associated with reminders to which the user typicallycancels and reminders to which the user typically responds. Forinstance, when the user typically responds (e.g., more than 50% of thetime) to reminders associated with a particular type of communication,the system 200 may lower the response rate threshold associated with theparticular type of communication.

In another example, a response rate threshold may be set at 60%. In thisexample, the system 200 may track the user's reaction to reminders setbased on the 60% threshold in the past. The system 200 may track whetheror not the user responded to the communication based on the reminder andthe response rate for the type of communication for which the reminderwas set. When the system 200 determines that the user typically responds(e.g., more than 50% of the time) to reminders for communicationsassociated with a response rate of 75% or higher, but typically does notrespond (e.g., less than 50% of the time) to reminders forcommunications associated with a response rate of lower than 75%, thesystem 200 may adjust the response rate threshold from 60% to 75%. Inthis regard, adjusting the response rate threshold automatically basedon the user's reaction to past reminders may help the user avoidunwanted reminders and further focus the reminders on communicationsthat are important to the user.

The system 200 determines whether to set a response reminder for thereceived communication based on the comparison (1830). For example, whenthe comparison reveals that the response rate exceeds the response ratethreshold, the system 200 determines to set a response reminder for thecommunication. When the comparison reveals that the response rate isless than the response rate threshold, the system 200 determines not toset a response reminder for the communication.

In response to a determination to set a response reminder for thereceived communication, the system 200 automatically sets a responsereminder using the response reminder time (1840). For instance, thesystem 200 automatically determines the response reminder time using oneor more of the techniques described throughout this disclosure and setsa response reminder for the communication using the determined responsereminder time. The system 200 may set the response reminder by storingreminder data in electronic storage that defines the response reminder.The reminder data may include an identification of the communication towhich the reminder corresponds, a time when the reminder should beprovided, and/or other information that should be included in thereminder (e.g., details of the communication to include with thereminder, such as sender, subject, time of receipt, etc.). The system200 provides a reminder to the user based on the set reminder data.

In response to a determination not to set a response reminder for thereceived communication, the system 200 handles the receivedcommunication without providing a response reminder (1850). Forinstance, the system 200 does not store reminder data for thecommunication and does not automatically provide a response reminder forthe communication.

FIG. 19 illustrates an example 1900 of determining whether to set areminder based on prior response rate data. As shown, the example 1900includes tracked response pattern data that has a sender column 1910, anaverage response time column 1920, and an average response rate column1930. The sender column 1910 includes data identifying senders ofcommunications to which a user has responded in the past. The averageresponse time column 1920 includes data indicating an average responsetime of the user for past communications received from the correspondingsender in the sender column 1910. The response rate column 1930 includesdata indicating a response rate of the user for past communicationsreceived from the corresponding sender in the sender column 1910. Forinstance, the response rate may be a percentage of past communicationsreceived from the corresponding sender in the sender column 1910 towhich the user responded.

In the example 1900, the tracked response pattern data includes a firstrow 1940 indicating that the user responds to communications sent fromSender 1 on average in one and a half hours and at a rate of 80%. Thetracked response pattern data also includes a second row 1950 indicatingthat the user responds to communications sent from Sender 2 on averagein one hour and at a rate of 24%. Although the tracked response patterndata includes two rows for ease of explanation, the tracked responsepattern data may include more rows and data corresponding to manydifferent senders.

In one example, the system 200 receives a first communication 1960 sentby Sender 1. In this example, the system 200 compares the response ratefor communications sent by Sender 1 (i.e., 80%) to a threshold responserate (e.g., 25%). Because the comparison reveals that the response ratefor communications sent by Sender 1 is greater than the thresholdresponse rate, the system 200 determines to set a reminder for the firstcommunication 1960.

In response to the determination to set a reminder for the firstcommunication 1960, the system 200 accesses the average response timedata in the row 1940 to use in setting a reminder time for the firstcommunication 1960. Because the first communication 1960 was received onJun. 6, 2009 at 4:35 PM and the user responds to communications sentfrom Sender 1 on average in one and a half hours, the system 200provides a reminder 1970 related to the first communication 1960 to theuser on Jun. 6, 2009 at 6:05 PM. The reminder 1970 includes a reminderportion that indicates that a response to the communication is overdue,a communication portion that provides details related to the firstcommunication 1960 to which the reminder corresponds, a respondinterface control 1972, and a modify interface control 1974. The respondinterface control 1972 enables the user to respond to the firstcommunication 1960 (e.g., by displaying a response communicationinterface, such as a response email composition interface that resultswhen a user selects a respond control) when the user selects the respondinterface control 1972 (e.g., using a mouse to select the respondinterface control 1972). The modify interface control 1974 enables theuser to modify the reminder 1970 (e.g., by displaying a modify reminderinterface) when the user selects the modify interface control 1974(e.g., using a mouse to select the modify interface control 1974). Forinstance, the user may use a modify reminder interface to extend thereminder time associated with the reminder 1970 (e.g., snooze thereminder 1970) or to cancel the reminder 1970. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 1970 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 1980sent by Sender 2. In this example, the system 200 compares the responserate for communications sent by Sender 2 (i.e., 24%) to a thresholdresponse rate (e.g., 25%). Because the comparison reveals that theresponse rate for communications sent by Sender 2 is less than thethreshold response rate, the system 200 determines not to set a reminderfor the second communication 1980. Accordingly, the system 200 does notprovides a reminder 1990 for the second communication 1980 because theuser has responded to past communications from Sender 2 at too low of arate and, therefore, the system 200 determines that providing a remindermay be more distracting to the user than helpful.

FIG. 20 illustrates an example of a communication inbox 2000. The inbox2000 displays a list of representations of communications received by arecipient. The inbox 2000 includes a reminder column that has reminderinformation related to each communication represented in the inbox 2000.

The reminder column provides an indication of overdue communications forwhich a reminder has been set, the reminder time has passed, and aresponse has not been sent. For example, the entry in the remindercolumn for the communication 2040 indicates that a response to thecommunication 2040 is one hour overdue. In another example, the entry inthe reminder column for the communication 2050 indicates that a responseto the communication 2050 is one day overdue.

The reminder column also provides an indication of due communicationsfor which a reminder has been set and a response is not yet due. Forexample, the entry in the reminder column for the communication 2010indicates that a response to the communication 2010 is due on January14. In another example, the entry in the reminder column for thecommunication 2030 indicates that a response to the communication 2030is due at 3 PM.

The reminder column further provides an indication of communications forwhich a response has been sent. For example, the entry in the remindercolumn for the communication 2070 indicates that a response to thecommunication 2070 has been sent.

In addition, the reminder column provides an indication ofcommunications for which a reminder has not been set. For example, theentry in the reminder column for the communication 2020 indicates that areminder has not been set for the communication 2020. A user may set areminder for the communication 2020 by selecting the set interfacecontrol displayed in the reminder column for the communication 2020. Inanother example, the entry in the reminder column for the communication2060 indicates that a reminder has not been set for the communication2060. A user may set a reminder for the communication 2060 by selectingthe set interface control displayed in the reminder column for thecommunication 2060.

The inbox 2000 includes reminder sort interface control 2080. Thereminder sort interface control 2080 sorts the inbox 2000 based onresponse reminders (e.g., data in the reminder column). As shown, theinbox 2000 is sorted based on attributes of the communications (e.g.,sender name, time of receipt, etc.). When the reminder sort interfacecontrol 2080 is selected based on user input, the system 200 sorts theinbox 2000 based on reminder data included in the reminder column. Thismay result in a different order of communications from the sorting basedon attributes of the communications. For example, when the reminder sortinterface control 2080 is selected, the system 200 may arrange overduecommunications first in the list in the inbox 2000 (e.g., ordered basedon how long a response has been overdue), arrange due communications forwhich a reminder has been set, but a response has not been sent and thereminder time has not lapsed second in the list in the inbox 2000 (e.g.,ordered based on when a response is due), arrange communications forwhich a reminder has not been set third in the list in the inbox 2000(e.g., ordered based on time of receipt), and arrange communications forwhich a response has been sent fourth in the list in the inbox 2000.

Applying this example to the communication inbox 2000 that is orderedbased on time of communication receipt, if a user where to select thereminder sort interface control 2080, the system 200 would reorder thecommunication inbox 2000. For instance, the system 200 may order thecommunication 2050 first, order the communication 2040 second, order thecommunication 2030 third, order the communication 2010 fourth, order thecommunication 2020 fifth, order the communication 2060 sixth, and orderthe communication 2070 seventh. This ordering may be quite differentthan ordering based on attributes of the received communications and mayassist the user in responding to old or stale communications bydisplaying representations of communications having overdue reminders atthe top of the list.

FIG. 21 illustrates an example of a process 2100 for handling a reminderfor a received communication based on electronic activity related to thereceived communication. The system 200 monitors for electronic activityrelated to a received communication for which a reminder is set (2110).The electronic activity may be any type of electronic activity that isrelated to the received communication. For example, the system 200monitors for the user sending a response to the received communication.In this example, the system 200 analyzes response communicationsinitiated by the user and, based on the analysis, determines whether thecommunication to which the user is responding has a response reminderset. The analysis may involve comparing communication identificationinformation (e.g., a message identifier) for the communication to whichthe user is responding with communication identification informationassociated with set response reminders.

The system 200 also may monitor for perception of the receivedcommunication by the user. For instance, the system 200 may monitor forwhether and when the user has selected a communication to cause thecommunication to be displayed or otherwise output. The system 200further may monitor for user input related to the reminder. Forinstance, the user input may be input to cancel the reminder or input toadjust the reminder time set for the reminder.

The system 200 may monitor for the user forwarding the receivedcommunication. For example, the system 200 analyzes communicationsforwarded by the user and, based on the analysis, determines whether theforwarded communication has a response reminder set. The analysis mayinvolve comparing communication identification information (e.g., amessage identifier) for the forwarded communication with communicationidentification information associated with set response reminders.

In some implementations, the system 200 monitors for communicationmanagement input/activity related to the received communication. Inthese implementations, the system 200 may monitor for deletion of thereceived communication from a communication system/inbox (e.g., userinput received from the user to delete the received communication). Thesystem 200 may monitor for storage or movement of the receivedcommunication in an interface for perceiving electronic communications.For instance, in the electronic mail context, the system 200 may monitorfor input from the user moving (e.g., storing/archiving) the receivedcommunication from an inbox to another folder in the electronic mailinterface. The system 200 may identify the folder to which the receivedcommunication was moved.

In some examples, the system 200 monitors for receipt of othercommunications related to the received communication. In these examples,the system 200 may monitor for further communications from the sender ofthe received communication. The system 200 also may monitor forresponses, to the sender of the received communication, from anotherrecipient of the received communication. The system 200 further maymonitor for additional communications from another recipient of thereceived communication. In these examples, the system 200 may compareincoming communications to data related to the received communicationand make a determination of whether the incoming communications arerelated to the received communication (e.g., from the same sender, fromanother recipient of the received communication, has the same subjectline, is part of a message string that includes the receivedcommunication, etc.). When an incoming communication is related to thereceived communication, the system 200 determines attributes of therelated incoming communication, such as sender, etc.

The system 200 modifies the set reminder for the received communicationin response to detection of particular electronic activity related tothe received communication (2120). For instance, the system 200 maycompare the particular electronic activity related to the receivedcommunication to a set of rules that describe reminder modification forparticular types of electronic activity and modify the set reminderbased on the comparison to the set of rules. The set of rules may bedefined by the communication system and/or user input received from theuser. The system 200 may modify the set reminder for the receivedcommunication by deleting the reminder or changing the reminder timeassociated with the reminder (e.g., extend, reset, accelerate, shorten,or adjust the reminder time).

The system 200 also may analyze detected electronic activity anddetermine that the detected electronic activity does not result inmodification of the reminder. For instance, the detected electronicactivity may not be part of the set of rules and, therefore, nomodification is made based on the detected electronic activity. Inaddition, the detected electronic activity may be part of the set ofrules, but the set of rules may indicate that the reminder should remainunchanged for the detected electronic activity.

In some examples, when the system 200 detects that the user has sent aresponse to the received electronic communication, the system 200deletes the set reminder for the received communication. In theseexamples, the system 200 deletes the set reminder for the receivedcommunication because the user has sent a response, thereby making thereminder unnecessary and, perhaps, confusing.

In some implementations, the system 200 may analyze a sent response tothe received communication and determine whether or not to delete theresponse reminder based on the analysis of the sent response. In theseimplementations, the system 200 may analyze a length of the responseand/or the content included in the response to determine whether theresponse was a full response to the communication or whether theresponse merely confirmed receipt and/or indicated that a full responsewould be forthcoming.

For instance, when the system 200 determines that a responsecommunication is relatively short (e.g., less than 50 words), the system200 determines that the response was not a full response and that thereminder associated with the received communication should not bedeleted. Alternatively, when the system 200 determines that a responsecommunication is relatively long (e.g., greater than 50 words), thesystem 200 determines that the response was a full response and that thereminder associated with the received communication should be deleted.

In another example, the system 200 may analyze the response for contentthat suggests that the response is not a full response and that anadditional response would be forthcoming. In this example, the system200 may scan the text of the response communication to attempt toidentify phrases that indicate that the response is not a full response,such as “I/we will get back to you” or “I/we will respond in duecourse.” When a phrase that indicates that the response is not a fullresponse is identified, the system 200 determines that the response isnot a full response and maintains the set response reminder. The system200 may consider a combination of factors (e.g., size, content, etc.) indetermining whether the response is a full response.

In addition, the system 200 may track past response behavior of the userin determining whether the response is a full response. For instance,the system 200 may determine whether the user typically sends multipleresponses to communications of a particular type. When the system 200determines that the user typically sends multiple responses, the system200 is more likely to determine that a first response is not a fullresponse. The system 200 also may track instances where a user sendsmultiple responses to a communication and identify attributes of thefirst response for use in identifying future responses that are not fullresponses. For example, the system 200 may determine a size of the firstresponse and identify phrases that typically occur in first responsessent by the user. In this example, the system 200 stores the sizeinformation and the identified phrases in electronic storage andconstructs a profile of response communications that are not fullresponses by the user. Then, when the system 200 detects the usersending a response to the received communication, the system 200accesses the profile, compares the response to the profile, anddetermines whether the response is a full response based on thecomparison. When the system 200 determines that the response is not afull response, the system 200 may maintain the set reminder and displaya message to the user indicating that the response reminder has beenmaintained for the received communication. The displayed message mayenable the user to delete or modify the response reminder. In addition,when the system 200 maintains the set reminder because the system 200determines that the user's response is not a full response, the system200 may update the reminder data such that, when the reminder isprovided to the user, the reminder indicates that the user responded tothe received communication, but that the system determined that theresponse was not a full response. The system 200 further may providedata related to the response in the reminder or provide a link to theresponse in the reminder, so that the user can quickly determine whetherthe system 200 was correct or whether the first response was a fullresponse and an additional response is not needed.

The system 200 also may modify the reminder based on detected perceptionof the received communication by the user. For instance, the system 200may reset the reminder time to correspond to the user's perception ofthe received communication, rather than the system's receipt of thereceived communication. The system 200 further may modify the reminderbased on detected user input related to the reminder. For instance, whenthe user input is input to cancel the reminder, the system 200 deletesthe reminder. When the user input is input to adjust the reminder timeset for the reminder, the system 200 adjusts the reminder time to matchthe user input.

The system 200 may modify the reminder based on detection of the userforwarding the received communication. For example, the system 200 mayextend the reminder time based on the detected forwarding. In thisexample, the system 200 may extend the reminder a particular amount oftime set by the user or set by the system 200. The particular amount oftime may be determined based on past response patterns of the user whenthe user has forwarded a communication for which a reminder has been setin the past. In other examples, the system 200 may delete the responsereminder based on the detected forwarding when the forwardedcommunication requests another user to handle or respond to the receivedcommunication.

In some implementations, the system 200 modifies the reminder based ondetected communication management input/activity related to the receivedcommunication. In these implementations, the system 200 may delete thereminder when the system 200 detects deletion of the receivedcommunication from a communication system/inbox or movement of thereceived communication out of an inbox and into a folder. The system 200may consider the folder to which the received communication was moved indetermining how to handle the reminder for the received communication.For instance, when the system 200 detects that the receivedcommunication has been moved to an archive folder, the system 200deletes the reminder corresponding to the received communication. Whenthe system 200 detects that the received communication has been moved toa follow up folder, the system 200 maintains the reminder correspondingto the received communication.

In some examples, the system 200 modifies the reminder based on detectedreceipt of other communications related to the received communication.In these examples, the system 200 may accelerate the reminder time whenthe system 200 detects receipt of another communication from the senderof the received communication because, in this case, the sender appearsto be anxious for a response. The system 200 may accelerate the remindera particular amount of time set by the user or set by the system 200.The particular amount of time may be determined based on past responsepatterns of the user when the user has received multiple communicationsfrom the same sender in the past.

The system 200 also may modify the reminder based on detected receipt ofa response, to the sender of the received communication, from anotherrecipient of the received communication. For instance, the system 200may delete the reminder based on detection of the response, to thesender of the received communication, from another recipient of thereceived communication. The system 200 further may modify the reminderbased on detected receipt of an additional communication from anotherrecipient of the received communication. For example, the system 200 mayaccelerate or extend the reminder time when the system 200 detectsreceipt of the additional communication from another recipient of thereceived communication. The system 200 may accelerate or extend thereminder a particular amount of time set by the user or set by thesystem 200. The particular amount of time may be determined based onpast response patterns of the user when the user has received anadditional communication from another recipient of a receivedcommunication in the past.

The system 200 handles the reminder for the received communication basedon any modification from monitoring electronic activity related to thereceived communication (2130). For instance, when the reminder isdeleted from electronic storage, the system 200 does not provide areminder related to the received communication. When the reminder timeof the reminder has been modified, the system 200 provides a reminderrelated to the received communication based on the modified remindertime, rather than the originally-set reminder time.

FIG. 22 illustrates an example 2200 of deleting a reminder for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2200 includes set reminderdata 2210. The set reminder data 2210 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. Although the set reminder data 2210 includes a single responsereminder for ease of explanation, the set reminder data 2210 may includemore response reminders corresponding to many different messages.

In the example 2200, the system 200 detects electronic activity 2220related to Message 1. The electronic activity 2220 is a detection thatthe user responded to Message 1 on Jun. 6, 2009 at 5:00 PM. Because theuser responded to Message 1, the system 200 deletes the responsereminder for Message 1 from the set reminder data 2230. Based on thedeletion, no reminder is provided to the user on Jun. 6, 2009 at 6:00 PMfor Message 1.

FIG. 23 illustrates an example 2300 of resetting a reminder time for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2300 includes set reminderdata 2310. The set reminder data 2310 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2310 includes a single response reminder for easeof explanation, the set reminder data 2310 may include more responsereminders corresponding to many different messages.

In the example 2300, the system 200 detects electronic activity 2320related to Message 1. The electronic activity 2320 is a detection thatthe user perceived (e.g., read) Message 1 on Jun. 6, 2009 at 5:30 PM.Because the user perceived Message 1 on Jun. 6, 2009 at 5:30 PM, thesystem 200 modifies the response reminder time for Message 1. Forinstance, based on the detected perception of Message 1, the system 200adjusts or resets, in the set reminder data 2330, the reminder time ofthe response reminder for Message 1 to Jun. 6, 2009 at 6:30 PM, which isone hour from the detected perception of Message 1. Based on theadjustment, a reminder for Message 1 is provided to the user on Jun. 6,2009 at 6:30 PM, rather than the originally set reminder time of Jun. 6,2009 at 6:00 PM.

FIG. 24 illustrates an example 2400 of extending a reminder time for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2400 includes set reminderdata 2410. The set reminder data 2410 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2410 includes a single response reminder for easeof explanation, the set reminder data 2410 may include more responsereminders corresponding to many different messages.

In the example 2400, the system 200 detects electronic activity 2420related to Message 1. The electronic activity 2420 is a detection thatthe user forwarded (e.g., sent to another user with additional content)Message 1 on Jun. 6, 2009 at 5:30 PM. Because the user forwarded Message1 on Jun. 6, 2009 at 5:30 PM, the system 200 modifies the responsereminder time for Message 1 by extending the reminder time a particularamount of time from the receipt of Message 1 (e.g., two hours fromreceipt or one additional hour from receipt) or extending the remindertime a particular amount of time from the forwarding of Message 1 (e.g.,one and a half hours from the forwarding). For instance, based on thedetected forwarding of Message 1, the system 200 extends, in the setreminder data 2430, the reminder time of the response reminder forMessage 1 to Jun. 6, 2009 at 7:00 PM. Based on the extension, a reminderfor Message 1 is provided to the user on Jun. 6, 2009 at 7:00 PM, ratherthan the originally set reminder time of Jun. 6, 2009 at 6:00 PM. Thesystem 200 may extend the reminder time based on the forwarding becausethe forwarding suggests that the user is working toward a response(e.g., asking a question to gather more information), but may need moretime to prepare the response.

FIG. 25 illustrates an example 2500 of deleting a reminder for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2500 includes set reminderdata 2510. The set reminder data 2510 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. Although the set reminder data 2510 includes a single responsereminder for ease of explanation, the set reminder data 2510 may includemore response reminders corresponding to many different messages.

In the example 2500, the system 200 detects electronic activity 2520related to Message 1. The electronic activity 2520 is a detection thatthe user deleted Message 1 on Jun. 6, 2009 at 5:40 PM. Because the userdeleted Message 1, the system 200 deletes the response reminder forMessage 1 from the set reminder data 2530. Based on the deletion, noreminder is provided to the user on Jun. 6, 2009 at 6:00 PM for Message1.

FIG. 26 illustrates an example 2600 of adjusting a reminder time for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2600 includes set reminderdata 2610. The set reminder data 2610 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2610 includes a single response reminder for easeof explanation, the set reminder data 2610 may include more responsereminders corresponding to many different messages.

In the example 2600, the system 200 detects electronic activity 2620related to Message 1. The electronic activity 2620 is input receivedfrom the user to set the response reminder time for Message 1 to aparticular time or to extend the response reminder time for Message 1for a particular amount of time. Based on the user input, the system 200modifies the response reminder time for Message 1. For instance, basedon the received user input related to Message 1, the system 200 sets, inthe set reminder data 2630, the reminder time of the response reminderfor Message 1 to Jun. 6, 2009 at 7:30 PM. The system 200 sets thereminder time to 7:30 PM because the received user input was to set thereminder time to 7:30 PM or to extend the reminder time for one and ahalf hours from the originally set reminder time. Based on themodification resulting from the user input, a reminder for Message 1 isprovided to the user on Jun. 6, 2009 at 7:30 PM, rather than theoriginally set reminder time of Jun. 6, 2009 at 6:00 PM.

FIG. 27 illustrates an example 2700 of modifying a reminder for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2700 includes set reminderdata 2710. The set reminder data 2710 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2710 includes a single response reminder for easeof explanation, the set reminder data 2710 may include more responsereminders corresponding to many different messages.

In the example 2700, the system 200 detects electronic activity 2720related to Message 1. The electronic activity 2720 is a detection thatanother recipient responded to Message 1 on Jun. 6, 2009 at 5:40 PM.Because another recipient responded to Message 1 on Jun. 6, 2009 at 5:40PM, the system 200 modifies the response reminder for Message 1. Forinstance, based on the detected response from another recipient ofMessage 1, the system 200 deletes, in the set reminder data 2730, theresponse reminder for Message 1 because the other recipient's responselikely answers the sender's question and alleviates the need for theuser to respond to Message 1. Based on the deletion, no reminder isprovided to the user on Jun. 6, 2009 at 6:00 PM for Message 1.

FIG. 28 illustrates an example 2800 of shortening a reminder time for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2800 includes set reminderdata 2810. The set reminder data 2810 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2810 includes a single response reminder for easeof explanation, the set reminder data 2810 may include more responsereminders corresponding to many different messages.

In the example 2800, the system 200 detects electronic activity 2820related to Message 1. The electronic activity 2820 is a detection thatanother message was received from the sender of Message 1 on Jun. 6,2009 at 5:30 PM. Because another message was received from the sender ofMessage 1 on Jun. 6, 2009 at 5:30 PM, the system 200 modifies theresponse reminder time for Message 1 by shortening the reminder time aparticular amount of time from the originally set reminder time (e.g.,fifteen minutes from the originally set reminder time) or shortening thereminder time a particular amount of time from the receipt of the othermessage (e.g., fifteen minutes from the receipt of the other message).For instance, based on the detected receipt of another message from thesender of Message 1, the system 200 shortens or reduces, in the setreminder data 2830, the reminder time of the response reminder forMessage 1 to Jun. 6, 2009 at 5:45 PM. Based on the reduction, a reminderfor Message 1 is provided to the user on Jun. 6, 2009 at 5:45 PM, ratherthan the originally set reminder time of Jun. 6, 2009 at 6:00 PM.

FIG. 29 illustrates an example 2900 of shortening a reminder time for areceived communication based on electronic activity related to thereceived communication. As shown, the example 2900 includes set reminderdata 2910. The set reminder data 2910 includes data indicating that aresponse reminder for Message 1 has been set for Jun. 6, 2009 at 6:00PM. The response reminder for Message 1 was set for Jun. 6, 2009 at 6:00PM because Message 1 was received at 5:00 PM and the user typicallyresponds to messages having a type of Message 1 in one hour. Althoughthe set reminder data 2910 includes a single response reminder for easeof explanation, the set reminder data 2910 may include more responsereminders corresponding to many different messages.

In the example 2900, the system 200 detects electronic activity 2920related to Message 1. The electronic activity 2920 is a detection thatanother message was received from another recipient of Message 1 on Jun.6, 2009 at 5:15 PM. In this example, the other message is not a responseto the sender of Message 1, does not include the sender of Message 1 inthe recipient list for the other message, and is related to Message 1(e.g., a forward of Message 1). Because another message was receivedfrom another recipient of Message 1 on Jun. 6, 2009 at 5:15 PM, thesystem 200 modifies the response reminder time for Message 1 byshortening the reminder time a particular amount of time from theoriginally set reminder time (e.g., thirty minutes from the originallyset reminder time) or shortening the reminder time a particular amountof time from the receipt of the other message (e.g., fifteen minutesfrom the receipt of the other message). For instance, based on thedetected receipt of another message from another recipient of Message 1,the system 200 shortens or reduces, in the set reminder data 2930, thereminder time of the response reminder for Message 1 to Jun. 6, 2009 at5:30 PM. Based on the reduction, a reminder for Message 1 is provided tothe user on Jun. 6, 2009 at 5:30 PM, rather than the originally setreminder time of Jun. 6, 2009 at 6:00 PM.

FIG. 30 illustrates an example of a process 3000 for automaticallysetting a response reminder time for a received communication based onmultiple types of the received communication. The system 200 receives acommunication for a user (3010). For example, the system 200 receives acommunication for a user using techniques similar to those discussedabove with respect to reference numeral 510.

The system 200 determines multiple types of the received communication(3020). For example, the system 200 determines a type of the receivedcommunication using techniques similar to those discussed above withrespect to reference numeral 520. In this example, the system 200determines that the received communication matches multiple trackedtypes.

The system 200 accesses, from electronic storage, response pattern dataassociated with each of the multiple types of the received communication(3030). For instance, the system 200 accesses response pattern dataassociated with a determined type of the received communication usingtechniques similar to those discussed above with respect to referencenumeral 530. In some examples, the system 200 may access, for each ofthe multiple types, individual response pattern data that tracks pastresponses to each of the multiple types (e.g., accessing first responsepattern data corresponding to a first type, accessing second responsepattern data corresponding to a second type, etc.). In other examples,the system 200 may track response patterns for communications havingmultiple types and the system 200 may access response pattern data forpast communications that match all of the multiple types. In theseexamples, when a received communication corresponds to first and secondtypes, the system 200 may access response pattern data for the user'spast response behavior for communications of the first and second types.For instance, the system 200 may store response pattern data thatindicates that the user responds to communications from Sender 1 havingthe content “Urgent” on average in five minutes, that the user respondsto communications from Sender 1 having the content “Code X” on averagein thirty minutes, that the user responds to communications from Sender2 having the content “Urgent” on average in sixty minutes, and that theuser responds to communications from Sender 2 having the content “CodeY” on average in four days. When the user receives a communication fromSender 1 having the content “Code X,” the system 200 accesses the thirtyminute average response time data that corresponds to communicationsmatching the multiple types.

The system 200 automatically sets a response reminder time for thereceived communication based on the accessed response pattern dataassociated with each of the multiple types of the received communication(3040). The system 200 automatically sets a response reminder time forthe received communication based on the accessed response pattern dataassociated with the determined type of the received communication usingtechniques similar to those discussed above with respect to referencenumeral 540. For example, when the system 200 tracks response patternsfor communications having multiple types, the system 200 may set thereminder time using a relative response time for communications havingthe multiple types and/or a day of week/time of day response pattern forcommunications having the multiple types as discussed above with respectto FIG. 16.

In some implementations, the system 200 tracks types of communicationsindividually such that the system 200 accesses individual responsepattern data for each of the multiple types. In these implementations,the accessed individual response pattern data may include a relativeresponse time for each of the multiple types of the receivedcommunication and a day of week/time of day response pattern for each ofthe multiple types of the received communication. Because the receivedcommunication corresponds to multiple relative response times andmultiple day of week/time of day response patterns, the system 200accounts for the multiple relative response times and multiple day ofweek/time of day response patterns in determining a response remindertime.

For example, when the accessed response pattern data includes multiplerelative response times, the system 200 may compute a combined relativeresponse time that accounts for each of the multiple relative responsetimes. In this example, the system 200 computes the combined relativeresponse time by, for example, computing an average of the multiplerelative response times or by determining a median of the multiplerelative response times.

When the accessed response pattern data includes multiple day ofweek/time of day response patterns, the system 200 may determine acombined day of week/time of day response pattern that accounts for eachof the multiple day of week/time of day response patterns. In thisexample, the system 200 may compare each of the multiple day ofweek/time of day response patterns to one another and identify portionsthat overlap. The system 200 may use the identified overlapping portionsas a combined day of week/time of day response pattern. In instances inwhich no overlapping portions exist, the system 200 may determine not touse the day of week/time of day response patterns or may determine acombined day of week/time of day response pattern by computing anaverage day of week/time of day response pattern or by selecting asubset of the multiple day of week/time of day response patterns. Thesystem 200 also may determine a combined day of week/time of dayresponse pattern by aggregating all of the multiple day of week/time ofday response patterns together.

In some examples, the response pattern data may have weights associatedwith different types of communications and the weights may be used incombining the response patterns for the multiple types. For instance,the system 200 may use the weights in computing a weighted average ofrelative response times (e.g., sender type may have a weight of two andcontent type may have a weight of one such that the sender typecontributes to the weighted average twice as much as the content type).The system 200 also may use the weights in selecting a subset of theresponse patterns to use in setting the reminder time. For example, ininstances in which no overlapping portions exist for multiple day ofweek/time of day response patterns, the system 200 may select the day ofweek/time of day response pattern having the highest weight to use insetting the reminder time.

In some implementations, the system 200 compares relative response timesto day of week/time of day response patterns in determining how to usethe multiple response patterns. For instance, the system 200 may useonly those relative response times that match the corresponding day ofweek/time of day response pattern. In addition, the system 200 may use arelative response time of a first type and a day of week/time of dayresponse pattern from a second type in setting the reminder time.

The system 200 also may determine whether or not to set a reminder forthe received communication based on a response rate for communicationshaving the multiple types. When the system 200 tracks response patternsfor communications having multiple types, the system 200 may determinewhether to set a reminder using a response rate for communicationshaving the multiple types as discussed above with respect to FIG. 18.When the system 200 tracks each of the multiple types individually, thesystem 200 may compute an average or median response rate based on themultiple response rates associated with the multiple types ofcommunications and use the computed response rate in determining whetherto set a response reminder for the received communication.

FIG. 31 illustrates an example 3100 of setting a reminder based on asender and content of a communication. As shown, the example 3100includes tracked response pattern data that has a type column 3110 andan average response time column 3120. The type column 3110 includes dataidentifying a type (e.g., sender or content) of communications to whicha user has responded in the past. The average response time column 3120includes data indicating an average response time of the user for pastcommunications having the corresponding type in the type column 3110.

In the example 3100, the tracked response pattern data includes a firstrow 3130 indicating that the user responds to communications having thecontent “Code X” on average in one hour. The tracked response patterndata also includes a second row 3132 indicating that the user respondsto communications having the content “Urgent” on average in ten minutes.The tracked response pattern data further includes a third row 3134indicating that the user responds to communications sent by Sender 1 onaverage in fifty minutes. In addition, the tracked response pattern dataincludes a fourth row 3136 indicating that the user responds tocommunications sent by Sender 2 on average in thirty minutes.

In one example, the system 200 receives a first communication 3140 sentby Sender 1 and having the content “Urgent.” In this example, the system200 determines that the first communication 3140 is sent by Sender 1 andhas the content “Urgent”, identifies the rows 3132 and 3134 in thetracked response pattern data corresponding to communications having thecontent “Urgent” and communications sent by Sender 1, respectively, andaccesses the average response time data from each of the rows 3132 and3134 in the tracked response pattern data. Because the firstcommunication 3140 was received on Jun. 6, 2009 at 6:35 PM and the userresponds to communications having the content “Urgent” on average in tenminutes and communications sent by Sender 1 on average in fifty minutes,the system 200 provides a reminder 3150 related to the firstcommunication 3140 to the user on Jun. 6, 2009 at 7:05 PM. For instance,the system 200 determines to account for both the detected content typeand the detected sender type in setting a reminder and determines theresponse reminder time by computing an average of the average responsetime data for communications having the content “Urgent” (10 minutes)and the average response time data for communications sent by Sender 1(50 minutes). The system 200 then adds the computed average (30 minutes)to the time of receipt (6:35 PM) and sets a time for the reminder 3150as a result of the addition (7:05 PM). The reminder 3150 includes areminder portion that indicates that a response to the communication isoverdue, a communication portion that provides details related to thefirst communication to which the reminder corresponds, a respondinterface control, and a modify interface control.

In another example, the system 200 receives a second communication 3160sent by Sender 2 and having the content “Urgent.” In this example, thesystem 200 determines that the second communication 3160 is sent bySender 2 and has the content “Urgent”, identifies the rows 3132 and 3136in the tracked response pattern data corresponding to communicationshaving the content “Urgent” and communications sent by Sender 2,respectively, and accesses the average response time data from each ofthe rows 3132 and 3136 in the tracked response pattern data. Because thesecond communication 3160 was received on Jun. 6, 2009 at 6:35 PM andthe user responds to communications having the content “Urgent” onaverage in ten minutes and communications sent by Sender 2 on average inthirty minutes, the system 200 provides a reminder 3170 related to thesecond communication 3160 to the user on Jun. 6, 2009 at 6:55 PM. Forinstance, the system 200 determines to account for both the detectedcontent type and the detected sender type in setting a reminder anddetermines the response reminder time by computing an average of theaverage response time data for communications having the content“Urgent” (10 minutes) and the average response time data forcommunications sent by Sender 2 (30 minutes). The system 200 then addsthe computed average (20 minutes) to the time of receipt (6:35 PM) andsets a time for the reminder 3170 as a result of the addition (6:55 PM).The reminder 3170 includes a reminder portion that indicates that aresponse to the communication is overdue, a communication portion thatprovides details related to the second communication to which thereminder corresponds, a respond interface control, and a modifyinterface control.

In yet another example, the system 200 receives a third communication3180 sent by Sender 2 and having the content “Code X.” In this example,the system 200 determines that the third communication 3180 is sent bySender 2 and has the content “Code X”, identifies the rows 3130 and 3136in the tracked response pattern data corresponding to communicationshaving the content “Code X” and communications sent by Sender 2,respectively, and accesses the average response time data from each ofthe rows 3130 and 3136 in the tracked response pattern data. Because thethird communication 3180 was received on Jun. 6, 2009 at 6:35 PM and theuser responds to communications having the content “Code X” on averagein one hour and communications sent by Sender 2 on average in thirtyminutes, the system 200 provides a reminder 3190 related to the thirdcommunication 3180 to the user on Jun. 6, 2009 at 7:20 PM. For instance,the system 200 determines to account for both the detected content typeand the detected sender type in setting a reminder and determines theresponse reminder time by computing an average of the average responsetime data for communications having the content “Code X” (60 minutes)and the average response time data for communications sent by Sender 2(30 minutes). The system 200 then adds the computed average (45 minutes)to the time of receipt (6:35 PM) and sets a time for the reminder 3190as a result of the addition (7:20 PM). The reminder 3190 includes areminder portion that indicates that a response to the communication isoverdue, a communication portion that provides details related to thethird communication to which the reminder corresponds, a respondinterface control, and a modify interface control.

FIG. 32 illustrates an example 3200 of determining whether to set areminder based on a sender group and priority designation of acommunication. As shown, the example 3200 includes tracked responsepattern data that has a type column 3210 and an average response ratecolumn 3220. The type column 3210 includes data identifying a type(e.g., sender group or priority designation) of communications to whicha user has responded in the past. The average response rate column 3220includes data indicating an average response rate of the user for pastcommunications having the corresponding type in the type column 3210.

In the example 3200, the tracked response pattern data includes a firstrow 3230 indicating that the user responds to communications fromsenders in Group 1 on average 20% of the time. The tracked responsepattern data also includes a second row 3232 indicating that the userresponds to communications from senders in Group 2 on average 70% of thetime. The tracked response pattern data further includes a third row3234 indicating that the user responds to communications having apriority designation of high on average 90% of the time. In addition,the tracked response pattern data includes a fourth row 3236 indicatingthat the user responds to communications having a priority designationof low on average 20% of the time.

In one example, the system 200 receives a first communication 3240 sentby a sender in Group 1 and having a priority designation of “Low.” Inthis example, the system 200 determines that the first communication3240 is sent by a sender in Group 1 and has the priority designation of“Low,” identifies the rows 3230 and 3236 in the tracked response patterndata corresponding to communications sent by a sender in Group 1 andcommunications having a priority designation of “Low,” respectively, andaccesses the average response rate data from each of the rows 3230 and3236 in the tracked response pattern data. Because the user responds tocommunications sent by a sender in Group 1 on average 20% of the timeand communications having a priority designation of “Low” on average 20%of the time, the system 200 determines not to set a reminder 3250 forthe first communication 3240. For instance, the system 200 determines toaccount for both the detected sender group and the detected prioritydesignation in determining whether to set a reminder and computes anaverage of the average response rate data for communications sent by asender in Group 1 (20%) and the average response rate data forcommunications having a priority designation of “Low” (20%). The system200 then compares the computed average (20%) to a rate threshold (e.g.,50%) and determines whether to set a reminder based on the comparison.In this case, the system 200 determines not to set a reminder 3250 forthe first communication 3240 because the comparison reveals that thecomputed average (20%) is less than the rate threshold (e.g., 50%).

In another example, the system 200 receives a second communication 3260sent by a sender in Group 1 and having a priority designation of “High.”In this example, the system 200 determines that the second communication3260 is sent by a sender in Group 1 and has the priority designation of“High,” identifies the rows 3230 and 3234 in the tracked responsepattern data corresponding to communications sent by a sender in Group 1and communications having a priority designation of “High,”respectively, and accesses the average response rate data from each ofthe rows 3230 and 3234 in the tracked response pattern data. Because theuser responds to communications sent by a sender in Group 1 on average20% of the time and communications having a priority designation of“High” on average 90% of the time, the system 200 determines to set areminder 3270 for the second communication 3260. For instance, thesystem 200 determines to account for both the detected sender group andthe detected priority designation in determining whether to set areminder and computes an average of the average response rate data forcommunications sent by a sender in Group 1 (20%) and the averageresponse rate data for communications having a priority designation of“high” (90%). The system 200 then compares the computed average (55%) toa rate threshold (e.g., 50%) and determines whether to set a reminderbased on the comparison. In this case, the system 200 determines to seta reminder 3250 for the second communication 3260 because the comparisonreveals that the computed average (55%) is greater than the ratethreshold (e.g., 50%), even though the response rate for Senders inGroup 1 does not exceed the rate threshold.

In yet another example, the system 200 receives a third communication3280 sent by a sender in Group 2 and having a priority designation of“Low,” identifies the rows 3232 and 3236 in the tracked response patterndata corresponding to communications sent by a sender in Group 2 andcommunications having a priority designation of “Low,” respectively, andaccesses the average response rate data from each of the rows 3232 and3236 in the tracked response pattern data. Because the user responds tocommunications sent by a sender in Group 2 on average 70% of the timeand communications having a priority designation of “Low” on average 20%of the time, the system 200 determines not to set a reminder 3290 forthe third communication 3280. For instance, the system 200 determines toaccount for both the detected sender group and the detected prioritydesignation in determining whether to set a reminder and computes anaverage of the average response rate data for communications sent by asender in Group 2 (70%) and the average response rate data forcommunications having a priority designation of “Low” (20%). The system200 then compares the computed average (45%) to a rate threshold (e.g.,50%) and determines whether to set a reminder based on the comparison.In this case, the system 200 determines not to set a reminder 3290 forthe third communication 3280 because the comparison reveals that thecomputed average (45%) is less than the rate threshold (e.g., 50%), eventhough one of the response rates exceeds the rate threshold.

FIG. 33 illustrates an example 3300 of setting a reminder based on asender and content of a communication. As shown, the example 3300includes tracked response pattern data that has a type column 3310, anaverage response time column 3320, and a time of day pattern column3325. The type column 3310 includes data identifying a type (e.g.,sender or content) of communications to which a user has responded inthe past. The average response time column 3320 includes data indicatingan average response time of the user for past communications having thecorresponding type in the type column 3310. The time of day patterncolumn 3325 includes data indicating a time of day range during whichthe user has typically responded (e.g., more than a threshold amount oftime) to past communications having the corresponding type in the typecolumn 3310.

In the example 3300, the tracked response pattern data includes a firstrow 3330 indicating that the user responds to communications having thecontent “Code X” on average in one hour during 10:00 AM to 2:00 PM. Thetracked response pattern data also includes a second row 3332 indicatingthat the user responds to communications having the content “Urgent” onaverage in ten minutes with no time of day response pattern (e.g., theuser responds relatively evenly through the day to communications havingthe content “Urgent”). The tracked response pattern data furtherincludes a third row 3334 indicating that the user responds tocommunications sent by Sender 1 on average in fifty minutes during 10:00PM to 12:00 AM. In addition, the tracked response pattern data includesa fourth row 3336 indicating that the user responds to communicationssent by Sender 2 on average in thirty minutes during 8:00 AM to 12:00PM.

In one example, the system 200 receives a first communication 3340 sentby Sender 1 and having the content “Urgent.” In this example, the system200 determines that the first communication 3340 is sent by Sender 1 andhas the content “Urgent”, identifies the rows 3332 and 3334 in thetracked response pattern data corresponding to communications having thecontent “Urgent” and communications sent by Sender 1, respectively, andaccesses the average response time data and the time of day pattern fromeach of the rows 3332 and 3334 in the tracked response pattern data.Because the first communication 3340 was received on Jun. 6, 2009 at6:35 PM and the user responds to communications having the content“Urgent” on average in ten minutes throughout the day and communicationssent by Sender 1 on average in fifty minutes during 10:00 PM to 12:00AM, the system 200 provides a reminder 3350 related to the firstcommunication 3340 to the user on Jun. 6, 2009 at 6:45 PM. For instance,the system 200 computes a reminder time separately for each of thecontent pattern (6:45 PM) and the sender pattern (7:25 PM), compares thecomputed content reminder time to the content time of day pattern (nopattern), and compares the computed sender reminder time to the sendertime of day pattern (10:00 PM to 12:00 AM). Based on the comparisons,the system 200 determines that the computed content reminder timecorresponds to the content time of day pattern and that the computedsender reminder time does not correspond to the sender time of daypattern. Based on the determination that the computed content remindertime corresponds to the content time of day pattern and that thecomputed sender reminder time does not correspond to the sender time ofday pattern, the system 200 determines to account for the detectedcontent type, but not the detected sender type, in setting the remindertime. In this regard, the system 200 sets a time for the reminder 3350as 6:45 PM. The reminder 3350 includes a reminder portion that indicatesthat a response to the communication is overdue, a communication portionthat provides details related to the first communication to which thereminder corresponds, a respond interface control, and a modifyinterface control.

In another example, the system 200 receives a second communication 3360sent by Sender 1 and having the content “Code X.” In this example, thesystem 200 determines that the second communication 3360 is sent bySender 1 and has the content “Code X”, identifies the rows 3330 and 3334in the tracked response pattern data corresponding to communicationshaving the content “Code X” and communications sent by Sender 1,respectively, and accesses the average response time data and the timeof day pattern from each of the rows 3330 and 3334 in the trackedresponse pattern data. Because the second communication 3360 wasreceived on Jun. 6, 2009 at 1:35 PM and the user responds tocommunications having the content “Code X” on average in one hour during10:00 AM to 2:00 PM and communications sent by Sender 1 on average infifty minutes during 10:00 PM to 12:00 AM, the system 200 provides areminder 3370 related to the second communication 3360 to the user onJun. 6, 2009 at 6:00 PM. For instance, the system 200 computes areminder time separately for each of the content pattern (2:35 PM) andthe sender pattern (2:25 PM), compares the computed content remindertime to the content time of day pattern (10:00 AM to 2:00 PM), andcompares the computed sender reminder time to the sender time of daypattern (10:00 PM to 12:00 AM). Based on the comparisons, the system 200determines that the computed content reminder time does not correspondto the content time of day pattern and that the computed sender remindertime does not correspond to the sender time of day pattern. Based on thedetermination that the computed content reminder time does notcorrespond to the content time of day pattern and that the computedsender reminder time does not correspond to the sender time of daypattern, the system 200 determines to account for the detected contenttype and the detected sender type in setting the reminder time. In thisregard, the system 200 computes an average time of day pattern (2:00 PM)from the ending time of the content time of day pattern and a beginningof the sender time of day pattern (10:00 PM). Accordingly, the system200 sets a time for the reminder 3370 as 6:00 PM. The reminder 3370includes a reminder portion that indicates that a response to thecommunication is overdue, a communication portion that provides detailsrelated to the second communication to which the reminder corresponds, arespond interface control, and a modify interface control.

In yet another example, the system 200 receives a third communication3380 sent by Sender 2 and having the content “Code X.” In this example,the system 200 determines that the third communication 3380 is sent bySender 1 and has the content “Code X”, identifies the rows 3330 and 3336in the tracked response pattern data corresponding to communicationshaving the content “Code X” and communications sent by Sender 2,respectively, and accesses the average response time data and the timeof day pattern from each of the rows 3330 and 3336 in the trackedresponse pattern data. Because the third communication 3380 was receivedon Jun. 6, 2009 at 8:55 AM and the user responds to communicationshaving the content “Code X” on average in one hour during 10:00 AM to2:00 PM and communications sent by Sender 2 on average in thirty minutesduring 8:00 AM to 12:00 PM, the system 200 provides a reminder 3390related to the third communication 3380 to the user on Jun. 6, 2009 at10:00 AM. For instance, the system 200 computes an average reminder time(9:40 AM or 45 minutes from message receipt) based on the contentaverage response time (one hour) and the sender average response time(thirty minutes), compares the average reminder time to the content timeof day pattern (10:00 AM to 2:00 PM), and compares the average remindertime to the sender time of day pattern (8:00 AM to 12:00 PM). Based onthe comparisons, the system 200 determines that the average remindertime does not correspond to the content time of day pattern and that theaverage reminder time corresponds to the sender time of day pattern. Inaddition, the system 200 determines that the average reminder time iswithin a threshold amount of time from the content time of day pattern(e.g., within thirty minutes from 10:00 AM) and that the content time ofday pattern overlaps with the sender time of day pattern. Accordingly,although the average reminder time corresponds to the sender time of daypattern, the system 200 determines to set the reminder to coincide withthe beginning of the content time of day pattern because the averagereminder time is within a threshold amount of time from the content timeof day pattern and the content time of day pattern and the sender timeof day pattern overlap at that point. Accordingly, the system 200 sets atime for the reminder 3390 as 10:00 AM. The reminder 3390 includes areminder portion that indicates that a response to the communication isoverdue, a communication portion that provides details related to thethird communication to which the reminder corresponds, a respondinterface control, and a modify interface control.

FIG. 34 illustrates an example of a process 3400 for storing forwardpattern data. The process 3400 is similar to the process 300, exceptthat the process 3400 deals with identifying patterns of a user's pasthistory of forwarding communications, rather than identifying patternsof a user's past history of responding to communications. The system 200receives communications for a user (3410). For example, the system 200receives communications for a user using techniques similar to thosediscussed above with respect to reference numeral 310.

The system 200 determines one or more types of the receivedcommunications (3420). For instance, the system 200 determines one ormore types of the received communications using techniques similar tothose discussed above with respect to reference numeral 320.

The system 200 monitors forward behavior by the user to the receivedcommunications for the user (3430). For example, the system 200 monitorsforward behavior by the user to the received communications for the userusing techniques similar to monitoring response behavior discussed abovewith respect to reference numeral 330. In this example, instead ofmonitoring responses to communications by the user, the system 200monitors for instances in which the user forwards communications to auser or a communications address that is different from the sender orthe sender's communication address.

The system 200 determines forward patterns of the user by communicationtype based on the monitoring (3440). The system 200 determines forwardpatterns of the user by communication type based on the monitoring usingtechniques similar to determining response behavior patterns discussedabove with respect to reference numeral 340. Instead of determiningpatterns by communication type for communications to which the user hasresponded, the system 200 determines patterns by communication type forcommunications the user has forwarded.

The system 200 stores, in electronic storage, forward pattern data forthe user by communication type based on the determined forward patterns(3450). For instance, the system 200 stores, in electronic storage,forward pattern data for the user by communication type based on thedetermined forward patterns using techniques similar to those discussedabove with respect to reference numeral 350.

FIG. 35 illustrates an example data structure 3500 that stores forwardpattern data. The data structure 3500 is similar to the data structure400 described above with respect to FIG. 4, except the data structure3500 tracks forward time (e.g., relative forward time, such as averageforward time), forward rate, and a time of day/day of week forwardpattern, rather than tracking response time, response rate, and a timeof day/day of week response pattern.

FIG. 36 illustrates an example of a process 3600 for automaticallysetting a forward reminder time for a received communication. Theprocess 3600 is similar to the process 500, except that the process 3600deals with setting a reminder to forward a communication based on auser's past history of forwarding communications, rather than setting areminder to respond to a communication based on a user's past history ofresponding to communications. The system 200 receives a communicationfor a user (3610). For example, the system 200 receives a communicationfor a user using techniques similar to those discussed above withrespect to reference numeral 510.

The system 200 determines a type of the received communication (3620).For instance, the system 200 determines a type of the receivedcommunication using techniques similar to those discussed above withrespect to reference numeral 520.

The system 200 accesses, from electronic storage, forward pattern dataassociated with the determined type of the received communication(3630). For instance, the system 200 accesses forward pattern dataassociated with the determined type of the received communication usingtechniques similar to those discussed above with respect to referencenumeral 530.

The system 200 automatically sets a forward reminder time for thereceived communication based on the accessed forward pattern dataassociated with the determined type of the received communication(3640). The system 200 automatically sets a forward reminder time forthe received communication based on the accessed forward pattern dataassociated with the determined type of the received communication usingtechniques similar to those discussed above with respect to referencenumeral 540.

FIG. 37 illustrates an example 3700 of setting a forward reminder basedon a sender of a communication. As shown, the example 3700 includestracked forward pattern data that has a sender column 3710 and anaverage forward time column 3720. The sender column 3710 includes dataidentifying senders of communications to which a user has forwarded inthe past. The average forward time column 3720 includes data indicatingan average forward time of the user for past communications receivedfrom the corresponding sender in the sender column 3710. In the example3700, the tracked forward pattern data includes a first row 3730indicating that the user forwards communications sent from Sender 1 onaverage in one and a half hours. The tracked forward pattern data alsoincludes a second row 3740 indicating that the user forwardscommunications sent from Sender 2 on average in one hour. Although thetracked forward pattern data includes two rows for ease of explanation,the tracked forward pattern data may include more rows and datacorresponding to many different senders.

In one example, the system 200 receives a first communication 3750 sentby Sender 1. In this example, because the first communication 3750 wasreceived on Jun. 6, 2009 at 4:35 PM and the user forwards communicationssent from Sender 1 on average in one and a half hours, the system 200provides a forward reminder 3760 related to the first communication 3750to the user on Jun. 6, 2009 at 6:05 PM. The reminder 3760 includes areminder portion that indicates that a forwarding action related to thecommunication is overdue, a communication portion that provides detailsrelated to the first communication to which the reminder corresponds, aforward interface control 3762, and a modify interface control 3764. Theforward interface control 3762 enables the user to forward the firstcommunication 3750 (e.g., by displaying a forward communicationinterface, such as a forward email composition interface that resultswhen a user selects a forward control) when the user selects the forwardinterface control 3762 (e.g., using a mouse to select the forwardinterface control 3762). The modify interface control 3764 enables theuser to modify the reminder 3760 (e.g., by displaying a modify reminderinterface) when the user selects the modify interface control 3764(e.g., using a mouse to select the modify interface control 3764). Forinstance, the user may use a modify reminder interface to extend thereminder time associated with the reminder 3760 (e.g., snooze thereminder 3760) or to cancel the reminder 3760. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 3760 or other information that effectuates areminder to the user.

In another example, the system 200 receives a second communication 3770sent by Sender 2. In this example, because the second communication 3770was received on Jun. 6, 2009 at 5:00 PM and the user forwardscommunications sent from Sender 2 on average in one hour, the system 200provides a forward reminder 3780 related to the second communication3770 to the user on Jun. 6, 2009 at 6:00 PM. Although the firstcommunication 3750 was received prior to the second communication 3770,the reminder 3780 is provided to the user prior to the reminder 3760because the user typically forwards communications sent by Sender 2faster than communications sent by Sender 1. The reminder 3780 includesa reminder portion that indicates that a forwarding action related tothe communication is overdue, a communication portion that providesdetails related to the second communication to which the remindercorresponds, a forward interface control 3782, and a modify interfacecontrol 3784. The forward interface control 3782 is similar to therespond interface control 3762 and the modify interface control 3784 issimilar to the modify interface control 3764.

Any of the techniques or interfaces described throughout this disclosureas being applicable to responses to communications and reminders forresponding to communications may be applied to forwarding actions forcommunication reminders for forwarding communications. For instance,techniques similar to those described with respect to process 1600,process 1800, process 2100, process 3000 may be applied in the contextof forwarding communications.

FIG. 38 illustrates an example of a process 3800 for storing outgoingcommunication pattern data. The process 3800 is similar to the process300, except that the process 3800 deals with identifying patterns of auser's past history of sending any type of outgoing communications,rather than identifying patterns of a user's past history of respondingto communications. The system 200 identifies outgoing communicationssent by a user (3810). For example, the system 200 identifies any timethe user sends an outgoing communication of any type. In this example,the system 200 detects, as part of the outgoing communications, when theuser originates an outgoing communication that is not part of a priormessage string, when the user responds to a previously-receivedcommunication, and when the user forwards a previously-receivedcommunication.

In addition, the system 200 identifies outgoing communications sentusing any type of communication medium the system 200 is capable ofmonitoring. For instance, the system 200 detects, as part of theoutgoing communications, when the user generates (e.g., originates,responds to, forwards, etc.) an outgoing communication using an emailcommunication medium, when the user generates an outgoing communicationusing an instant message communication medium, when the user generatesan outgoing communication using a text or SMS message communicationmedium, and when the user generates an outgoing communication using avoice phone call communication medium.

The system 200 determines one or more types of the outgoingcommunications (3820). For instance, the system 200 determines one ormore types of the outgoing communications using techniques similar tothose discussed above with respect to reference numeral 320.

The system 200 monitors outgoing communication behavior by the user(3830). For example, the system 200 monitors outgoing communicationbehavior by the user using techniques similar to monitoring responsebehavior discussed above with respect to reference numeral 330. In thisexample, instead of monitoring responses to communications by the user,the system 200 monitors for any instances in which the user generates(e.g., sends) an outgoing communication.

The system 200 determines outgoing communication patterns of the user bycommunication type based on the monitoring (3840). The system 200determines outgoing communication patterns of the user by communicationtype based on the monitoring using techniques similar to determiningresponse behavior patterns discussed above with respect to referencenumeral 340. Instead of determining patterns by communication type forcommunications to which the user has responded, the system 200determines patterns by communication type for all outgoingcommunications the user has sent.

The system 200 stores, in electronic storage, outgoing communicationpattern data for the user by communication type based on the determinedoutgoing communication patterns (3850). For instance, the system 200stores, in electronic storage, outgoing communication pattern data forthe user by communication type based on the determined outgoingcommunication patterns using techniques similar to those discussed abovewith respect to reference numeral 350.

FIG. 39 illustrates an example data structure 3900 that stores outgoingcommunication pattern data. The data structure 3900 is similar to thedata structure 400 described above with respect to FIG. 4, except thedata structure 3900 tracks outgoing communication time (e.g., averageoutgoing communication time) and a time of day/day of week outgoingcommunication pattern, rather than tracking response time, responserate, and a time of day/day of week response pattern.

FIG. 40 illustrates an example of a process 4000 for automaticallysetting a reminder time for outgoing communications. The process 4000 issimilar to the process 500, except that the process 4000 deals withsetting a reminder to send any type of outgoing communication based on auser's past history of sending outgoing communications, rather thansetting a reminder to respond to a communication based on a user's pasthistory of responding to communications. The system 200 accesses, fromelectronic storage, outgoing communication pattern data associated withone or more types of communications (4010). For instance, the system 200accesses, from electronic storage, outgoing communication pattern dataassociated with one or more types of communications using techniquessimilar to those discussed above with respect to reference numeral 530.

The system 200 automatically sets a reminder time for outgoingcommunications associated with the one or more types of communicationsbased on the accessed outgoing communication pattern data (4020). Thesystem 200 automatically sets a reminder time for outgoingcommunications associated with the one or more types of communicationsbased on the accessed outgoing communication pattern data usingtechniques similar to those discussed above with respect to referencenumeral 540. For instance, each time the user sends an outgoingcommunication of a particular type, the system 200 updates the outgoingcommunication pattern data associated with the particular type andautomatically sets, based on the updated outgoing communication patterndata, a reminder time for a new reminder for outgoing communicationsassociated with the particular type.

In some examples, the system 200 evaluates set reminders periodically.In these examples, the system 200 may evaluate set reminders every hour,every day (e.g., every twenty-four hours, once a week, etc.). The usermay define the period/frequency the system 200 uses to evaluate setreminders and make a determination of whether an outgoing communicationfor a particular type of communication is overdue. Differentperiods/frequencies may be used for different types of communications(e.g., sender-based reminders may be evaluated more frequently thancontent-based reminders).

In some implementations, the system 200 evaluates set reminders inresponse to an event. In these implementations, the system 200 mayaccess the evaluate set reminders when (e.g., each time) the userinitiates use of a communication system (e.g., logs into, accesses overa network, launches on a local device, etc.). In addition, the system200 may evaluate set reminders when (e.g., each time) the user initiatesa new communication (e.g., activates a new email button, dials atelephone number, etc.) or the user begins to send any type of outgoingcommunication (e.g., activates a respond email button, activates aforward email button, etc.).

FIG. 41 illustrates an example 4100 of setting an outgoing communicationreminder based on a sender type. As shown, the example 4100 includestracked outgoing communication pattern data that has a sender column4110 and an average communication time column 4120. The sender column4110 includes data identifying senders of communications to which a userhas communicated with in the past. The average communication time column4120 includes data indicating an average time (e.g., period) betweenpast outgoing communications the user has sent to the correspondingsender in the sender column 4110. In the example 4100, the trackedoutgoing communication pattern data includes a first row 4130 indicatingthat the user sends outgoing communications to Sender 1 on average everyten days. The tracked outgoing communication pattern data also includesa second row 4140 indicating that the user sends outgoing communicationsto Sender 2 on average every month. Although the tracked outgoingcommunication pattern data includes two rows for ease of explanation,the tracked outgoing communication pattern data may include more rowsand data corresponding to many different senders.

In one example, the system 200 determines 4150 that the lastcommunication the user sent to Sender 1 was on Jun. 1, 2009. In thisexample, because the last communication the user sent to Sender 1 was onJun. 1, 2009 and the user sends outgoing communications to Sender 1 onaverage every ten days, the system 200 provides an outgoingcommunication reminder 4160 related to Sender 1 to the user on Jun. 11,2009. The reminder 4160 includes a reminder portion that indicates thatan outgoing communication to Sender 1 is overdue, a send interfacecontrol 4162, and a modify interface control 4164. The send interfacecontrol 4162 enables the user to send a communication to Sender 1 (e.g.,by displaying a send communication interface, such as a new emailcomposition interface that includes an email address of Sender 1) whenthe user selects the send interface control 4162 (e.g., using a mouse toselect the send interface control 4162). The modify interface control4164 enables the user to modify the reminder 4160 (e.g., by displaying amodify reminder interface) when the user selects the modify interfacecontrol 4164 (e.g., using a mouse to select the modify interface control4164). For instance, the user may use a modify reminder interface toextend the reminder time associated with the reminder 4160 (e.g., snoozethe reminder 4160) or to cancel the reminder 4160. Other examples mayprovide a different combination (e.g., a subset) of the informationprovided in the reminder 4160 or other information that effectuates areminder to the user.

In another example, the system 200 determines 4170 that the lastcommunication the user sent to Sender 2 was on May 10, 2009. In thisexample, because the last communication the user sent to Sender 2 was onMay 10, 2009 and the user sends outgoing communications to Sender 2 onaverage every month, the system 200 provides an outgoing communicationreminder 4180 related to Sender 2 to the user on Jun. 10, 2009. Thereminder 4180 includes a reminder portion that indicates that anoutgoing communication to Sender 2 is overdue, a send interface control4182, and a modify interface control 4184. The send interface control4182 is similar to the send interface control 4162 and the modifyinterface control 4184 is similar to the modify interface control 4164.

Any of the techniques or interfaces described throughout this disclosureas being applicable to responses to communications and reminders forresponding to communications may be applied to outgoing communicationsand reminders for sending outgoing communications. For instance,techniques similar to those described with respect to process 1600,process 2100, process 3000 may be applied in the context of outgoingcommunications.
